Water → Benzphetamine Hydrochloride

Participants

Reaction Steps

Benzphetamine hydrochloride is prepared in typical fashion in toluene. After reaction of methamphetamine with benzyl chloride in the presence of sodium carbonate, the reaction mass contained 28.76 g (0.1202 mole) of the acid salt which was a yield of 82.5%. To the reaction mass were added 100 g of deionized water. The mixture was stirred to dissolve the salts and then transferred to a separatory funnel. The reaction flask was rinsed with 50 g of water and 65 g of toluene. The rinsings were added to the separatory funnel. The layers were separated into a 169.5 g water layer and a 104.2 g of organic layer. The water layer was extracted twice with 27 g portions of toluene. The organic layers were combined bringing the total amount of organic medium to 156.1 g. The combined toluene portions were then washed with 33 g of deionized water.
