Reaction Conditions

Reaction Steps

To a solution of 8-benzyl-3-(2-methylpyrrolidin-1-yl)-6,7,8,9-tetrahydropyrazino[2,3-f][1,4]oxazepine (0.51 g) in methanol (15 mL) was added 20% Pd(OH)2/C (0.08 g), and the mixture was stirred under a hydrogen atmosphere at 50° C. for 1 hr. The reaction mixture was filtered, and the filtrate was concentrated. To a solution of the obtained crude product in ethyl acetate (15 mL) was added a 4 N hydrogen chloride-ethyl acetate solution (430 μL), and the mixture was stirred for 30 min. The reaction mixture was filtered, and the obtained crystals were purified by recrystallization (methanol-ethyl acetate) to give the title compound (0.30 g, 71%) as a colorless powder.
