실험 절차

(R)-7-[3-tert-Butoxycarbonylamino-4-(2,4,5-trifluoro-phenyl)-butyryl]-3-trifluoromethyl-5,6,7,8-tetrahydro-imidazo[1,5-a]pyrazine-1-carboxylic acid 2a (180 mg, 0.33 mmol) was dissolved in 10 mL of dichloromethane, followed by addition of butylamine hydrochloride (193 mg, 2.64 mmol), bis(2-oxo-3-oxazolidinyl)phosphinic chloride (167 mg, 0.66 mmol) and triethylamine (100 mg, 0.99 mmol). The reaction mixture was stirred 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. The resulting residue was purified by silica gel column chromatography to obtain the title compound (R)-[3-(1-butylcarbamoyl-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 43a (120 mg, yield 60%) as a white solid.
