실험 절차

(R)-[3-(1-Acetyl-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 27h (0.3 g, 0.55 mmol) was dissolved in 2 mL of ethyl acetate under stirring. A solution of 2.4 N hydrochloric acid in 5 mL of ethyl acetate was then added to the above solution. The reaction mixture was reacted at room temperature and monitored by thin layer chromatography until the disappearance of the starting materials. The reaction mixture was concentrated under reduced pressure. The resulting residue was purified by silica gel column chromatography to obtain the title compound (R)-1-(1-acetyl-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 27 (0.15 g, yield 57%) as a white solid.
