Versuchsvorschrift

(R)-7-[3-tert-Butoxycarbonylamino-4-(2,4,5-trifluoro-phenyl)-butyryl]-8-methyl-3-trifluoromethyl-5,6,7,8-tetrahydro-imidazo[1,5-a]pyrazine-1-carboxylic acid methyl ester 39d (0.23 g, 0.4 mmol) was added into the reaction flask. A solution of 2.3 N hydrochloric acid in 5 mL of ethyl acetate was then added to the flask. The reaction mixture was stirred at room temperature for 2 hours and monitored by thin layer chromatography until the disappearance of the starting materials. The reaction mixture was concentrated under reduced pressure to obtain the title compound (R)-7-[3-amino-4-(2,4,5-trifluoro-phenyl)-butyryl]-8-methyl-3-trifluoromethyl-5,6,7,8-tetrahydro-imidazo[1,5-a]pyrazine-1-carboxylic acid methyl ester hydrochloride 39 (0.205 g, yield 100%) as a white solid.
