Reaction Steps
Typically, the tetrahydroisoquinoline was suspended or dissolved in a cosolvent such as tetrahydrofuran ort-butyl alcohol. This mixture was cooled to −10° C. and methylamine was added and the temperature was maintained at −10° C. The lithium metal was charged in portions and the reaction mixture was stirred at −10° C. for another 30 minutes to about 2 hours after sufficient lithium metal was charged. The reaction mixture was warmed to room temperature and then added to water to produce the product hexahydroisoquinoline as a precipitate.
