실험 절차

7-Tert-butoxycarbonyl-3-(trifluoromethyl)-6,8-dihydro-5H-imidazo[1,5-a]pyrazine-1-carboxylic acid 20a (330 mg, 1 mmol) was dissolved in 5 mL of N, N-dimethylformamide, followed by addition of O-(1-benzotriazolyl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (756 mg, 2 mmol), cyclopropylmethylamine (142 mg, 2 mmol) and N,N-diisopropylethylamine (0.5 mL, 3 mmol). After stirring for 12 hours, the reaction mixture was concentrated under reduced pressure and added with 50 mL of ethyl acetate and washed successively with saturated ammonium chloride (15 mL×3) and saturated sodium chloride solution (10 mL). The organic phase was collected, dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated under reduced pressure to obtain crude tert-butyl 1-(cyclopropylmethylc arb amoyl)-3-(trifluoromethyl)-6,8-dihydro-5H-imidazo[1,5-a]pyrazine-7-carboxylate 24a (300 mg) as a brown-red oil. The product was used directly in the next reaction without purification.
