Procedure
(R)-[3-[1-(4-Acetyl-piperazine-1-carbonyl)-3-trifluoromethyl-5,6-dihydro-8H-imidazo[1,5-a]pyrazin-7-yl]-3-oxo-1-(2,4,5-trifluoro-benzyl)-propyl]-carbamic acid tert-butyl ester 17a (0.08 g, 0.12 mmol) and 2 mL of ethyl acetate were added into the reaction flask. A solution of 2.7 N hydrochloric acid in 2 mL of ethyl acetate was then added to the flask. The reaction mixture was reacted at room temperature overnight 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)-1-[1-(4-acetyl-piperazine-1-carbonyl)-3-trifluoromethyl-5,6-dihydro-8H-imidazo[1,5-a]pyrazin-7-yl]-3-amino-4-(2,4,5-trifluoro-phenyl)-butan-1-one hydrochloride 17 (70 mg, yield 98%) as a white solid.
