実験手順

To a solution of cis-pyrazolo[1,5-a]pyrimidine-3-carboxylic acid {3-(5-chloro-2-difluoromethoxyphenyl)-1-[2-(hexahydropyrrolo[3,4-c]pyrrol-2-yl)-2-oxoethyl]-1H-pyrazol-4-yl}amide (100 mg, 0.18 mmol) in 2,2,2-trifluoroethanol (3 mL) was added cyclopropanecarbaldehyde (67 μL, 0.90 mmol). After stirring at room temperature for 15 minutes, sodium borohydride (21 mg, 0.54 mmol) was added and the reaction was heated at 90° C. for 2 hours. MeOH was added to quench the reaction and the mixture was loaded onto an SCX-2 cartridge which had been conditioned with MeOH. After flushing with MeOH, the product was eluted with 2M ammonia in MeOH. Evaporation gave a crude product which was purified by HPLC (Method 1). The pure fractions loaded onto an SCX-2 cartridge which had been conditioned with MeOH. After flushing with MeOH, the product was eluted with 2M ammonia in MeOH. Evaporation gave the title compound as a free base which was crystallised from MeOH/Et2O and obtained as a yellow solid (55 mg, 50%).
