Versuchsvorschrift

To a solution of (6R)-8-benzyl-6-(methoxymethyl)-3-[2-(methoxymethyl)pyrrolidin-1-yl]-6,7,8,9-tetrahydropyrazino[2,3-f][1,4]oxazepine (329 mg) in methanol (10 mL) was added 20% Pd(OH)2/C (40 mg), and the mixture was stirred under a hydrogen atmosphere at 50° C. for 3 hr. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. To a solution of the obtained crude product in ethyl acetate (10 mL) was added a 4 N hydrogen chloride-ethyl acetate solution (227 μL), and the mixture was stirred for 30 min. The reaction mixture was filtered, and the obtained crystals were washed with ethyl acetate to give the title compound (155 mg, 54%).
