Reaction Steps

Pyrrolidine (560 mg, 8 mmol), methyl 3-(trifluoromethyl)-5,6,7,8-tetrahydroimidazo[1,5-a]pyrazine-1-carboxylate 3b (400 mg, 1.60 mmol) and 0.4 mL of H2O were mixed in a sealed tube. After stirring at 50° C. for 4 hours, the reaction mixture was concentrated under reduced pressure to obtain crude pyrrolidin-1-yl-[3-(trifluoromethyl)-5,6,7,8-tetrahydroimidazo[1,5-a]pyrazin-1-yl]methanone 18a (460 mg) as a light yellow solid. The product was used directly in the next reaction without purification.
