Your rx isn't that large. Put that inexpensive cold finger condenser on this 500ml https://www.amazon.com/Laboy-2-neck-Reaction-Stopcock-Joints/dp/B010BA2VLE
Forget the isopropyl it is not a part of this reduction. Stick to how this rx was designed. Use THF. Small scale under the radar. If it gets away (or when) you will survive. It not like you can call 911 for help. BTDT
The lithium-ammonia-ammonium chloride method is the addition of the benzyl alcohol, in our case ephedrine OR pseudoephedrine free base in THF to a solution of lithium in ammonia, and then the resultant mixture is rapidly quenched with ammonium chloride. The benzyl alcohols yield exclusively the corresponding aromatic hydrocarbon in our case D-Methamphetamine
I don't know how to post a picture on here. The illustrations are what stands out because they show exactly what we hunted through those citations praying to see. A reaction that reduces the OH to H and there are tables showing that this reduction does exactly that with out over reduction.
Ok last century this was ground breaking. You needed to acquire a full blow hazmat suit and respirator. You also needed to steal ammonia cylinders from a farm or freezer repair shop. The farm supplier would not sell it to you in CA. Feed stock was easy. This was bucket chemistry at it's best. Lying the cylinder on its side, you add your Ephed or pseudo free base in THF to the bucket. Prepare your lithium strips and place them in solvent. You then put on you full hazmat suit and respirator. The ammonia comes out liquid from the tank on it's side. Every bit of your body is encased in the hazmat suit. You would find out very fast if it was not when you open the valve on the tank. The ammonia hose goes right in the bucket. Call it using an excess of ammonia because you a put enough in there to get the job done as it is spitting, hissing and putting off a ghastly deadly cloud. You added the lithium to the bucket and stirred it until it the Li devolved. Put the lid on the bucket gave it 10 minutes. Pulled the lid and sprinkled in the ammonia chloride with stirring. Then you walked away leaving the ammonia to evaporate. Absolutely poisoning the work site. The narco swine used to demonstrate this reaction using a glass baking pan wearing their full hazmat gear. It doesn't take much meth to Marques test orange.
I digress. There is no longer an abundance of ammonia cylinders to be had and pseudo is tight. This reaction can be done on a very small scale in a home made fume closet. Of course you will be very careful to assemble your $200 worth of glassware (see online book store) that you have no leaks and and the reaction proceeds exactly as planned. But do it in the damn fume closet anyway. Scaling back the reaction to use your government allowed 7 grams go pseudo per month and it will fit nicely in the 500 ml reaction flask above. Taking due diligence building you fume closet it will handle it.
