Procedure
To a solution of tert-butyl [(2R,3S,5R)-2-(2,5-difluorophenyl)-5-(4,6-dihydropyrrolo[3,4-c]pyrazol-5(1H)-yl)-1-methyl-6-oxopiperidin-3-yl]carbamate (55.5 mg, 0.128 mmol) in dichloromethane (5 mL) at room temperature, triethylamine (0.045 mL, 0.320 mmol) and methanesulfonyl chloride (0.011 mL, 0.147 mmol) were added. The mixture was stirred for 1 h at room temperature. The residue was purified by prep TLC on silica gel, eluting with EtOAc/MeOH/NH4OH (90/9/1) to give first eluting isomer as isomer A and second eluting isomer as isomer B. Isomer A was treated with TFA/CH2Cl2=1:1 for 1 h to give the title compound. (LC-MS: 411.92 (M+1).
