Reaction Steps

An ethanol solution containing 20.0 g. (0.067 mole) of 4-amino-N-(1-cyclohexyl-3-pyrrolidinyl)-N-methylbenzamide was treated with 4.94 g. (0.037 mole) of (-)-malic acid and the solution was refrigerated overnight. The crystalline material which separated (m.p. 147°-157° C.) was recrystallized twice from ethanol to give 5.0 g. crystals which melted at 162°-163° C. Rotation [α]D30 : -22.65 (water).
