실험 절차

To a solution of (S)-methyl 4-(8-((2,4-dimethoxybenzyl)amino)-3-(2-thioxopiperidin-3-yl) imidazo[1,5-a]pyrazin-1-yl)benzoate (600 mg, 1.13 mmol) in THF (20 mL) was added cyclopropanecarbohydrazide (339 mg, 3.39 mmol) and Hg(OAc)2 (360 mg, 1.13 mmol). The mixture was stirred at RT for 20 minutes and then heated to 65° C. overnight. The reaction mixture was filtered and the filtrate was evaporated, the residue was purified by column chromatography on silica gel eluted with EA:DCM:THF=1:1:1 to give (S)-methyl 4-(3-(3-cyclopropyl-5,6,7,8-tetrahydro-[1,2,4]triazolo[4,3-a]pyridin-8-yl)-8-((2,4-dimethoxybenzyl)amino)imidazo[1,5-a]pyrazin-1-yl)benzoate (300 mg, yield 46%).
