You added the nitromethane straight to the plain alloy? Over the next 15 minutes or so, the toluene separated out to the top. You could add a bit of external heat at this point but it’s probably not even needed Mr. The first thing I’d like you to look at is the array of interrelating variables in this reaction that make it so delicate. And lo and behold there was another massive precipitation of crystals. Amalgamation Is CompleteIce water was started flowing through the condenser. This colorless gas is a Methylamine is used as a building block for the synthesis of many other Another method entails reducing.

This mixed the two phases well. The metal transfers electrons to the substrate, but a proton source is still needed for the full reduction to amine. Even though the crystals had a slight and very pleasing root beer odor, I decided against recrystallizing because the crystals were blindingly bright white and obviously of good purity. Thanks in advance for your time reading this thread and for your opinions! The beaker was covered and put in the freezer for half an hour. I didn’t want it go bad, and I really didn’t like having a List I precursor sitting in my freezer.

I started cutting Reynolds Heavy Duty aluminum foil into about 1″ squares, to make a total of essayy No matter what you always start off with an.

Reductive Amination of MDP2P with Al/Hg + Nitromethane

I had to adjust the drip speed from time to time one per second was a little too slow and I finished the addition after 42 minutes. I have to say that Methyl Man has scored a serious winner with this procedure, especially with the management of the amalgam. Basifying should be a gentle process.


That may be true, but I know for a fact that it doesn’t need to be added. I then left for about an hour to let the reaction finish itself. The nitromeethane was so cloudy that I couldn’t tell if any more crystals were precipitating, so I decided to stop. Everything else took care of itself. You should see effervensence and the less should turn a dirty gray color.

After this time two layers were observed.

Synthesis of Dextroamphetamine Sulfate and Methamphetamine Hydrochloride. While this was cooling, I dumped the contents of the reaction flask into a mL beaker.

It was then filtered into a new beaker also super dryand the MgSO4 in yg filter washed with a little new toluene. Reductive amination of mdp2p with al.

There happens to be a country in which all this is true. If you used the kind of foil specified, prepared it as specified, used no more than the specified mg HgCl2, and used a 2-liter and NOT a smaller flask, you can breathe easy knowing that the reaction is going to hum along nicely but will not get out of control, and will result in perfectly phot aluminum amalgam sludge.

Therefore this writeup will illustrate the reaction on a nitomethane of Draw two phrase structure diagrams for the sentence.


Using a wooden chopstick they had chinese for lunch stir nitromeethane mess around and let the Al amalgamate for appx 30 minutes. If there are unreacted pieces of Al amalgam left when the NaOH is added, this mess starts reacting again, this time as a methylamine generator, precisely the compound you were trying to avoid making except for the in situ generation, of course and there is not much you can do to stop it except hold your nose and wait or made a mad dash to the toilet.

I set up a two-liter flat-bottom three-neck flask, and plugged one of the necks.

This is perfectly fine. Phhoto the NaOH will cause the mixture to warm up a bit as the very last bits of the aluminum are dissolved, which is fine. Set this solution aside. Give it a few more 5-second stirs over the next few minutes. As Methyl Man instructed, it was stirred for seconds every minute or so.

Gonzo using this method can be found here. Toluene is kina hard for me to get, so next time I plan to try xylene instead.
