Versuchsvorschrift

To a solution of (2R)-4-[4-fluoro-2-(trifluoromethyl)phenyl]-2-methyl-1-[(3-piperazin-1-ylphenyl)sulfonyl]piperazine (120 mg, 0.247 mmol) in MeOH (2 mL) was added CH3CHO (12 mg, 0.27 mmol), HOAc (17.7 μL, 0.3 mmol) and NaBH3CN (8 mg, 0.125 mmol) at room temperature. The resultant mixture was stirred till disappearance of starting material as monitored by LCMS. The solvent was removed. The crude product was purified by SiO2 column eluted with DCM/MeOH to give the desired product as a light yellow solid (116 mg, 100%). HRMS: calcd for C24H30F4N4O2S+H+, 515.20983. found (ESI-FTMS, [M+H]1+), 515.20891.
