Participants

Reaction Steps

To a cooled solution of 4-tert-butyl-N-[4-chloro-2-((S)-4-pyrrolidin-3-yl-4H-[1,2,4]triazol-3-yl)-phenyl]-benzenesulfonamide (200 mg, 0.43 mmol) in MeOH (5 Ml) was added acetone (0.048 mL, 0.65 mmol) and then NaCNBH3 (0.054 g, 0.86 mmol). The reaction mixture was stirred at room temperature for 2 h, evaporated to dryness, adsorbed onto silica gel, and purified by automated normal-phase chromatography (50% MeOH in EtOAc) and then preparative HPLC (20→95% CH3CN in H2O with 0.1% TFA). The pure fractions were combined and lyophilized to obtain title compound as a powder: MS (ES) M+H expected 502.0, found 502.1.
