Procedure

To a solution of tert-butyl 4-cyano-4-{(3S)-3-methyl-4-[6-(trifluoromethyl)-2,3-dihydro-1H-inden-1-yl]piperazin-1-yl}piperidine-1-carboxylate (0.72 g, 1.3 mmol) in THF (20 mL) was added a 3 M solution of methylmagnesium bromide in ether (4.0 mL). After being stirred at room temperature overnight, the reaction was quenched by addition of water. The resulting solution was extracted with EtOAc twice. The combined EtOAc layers were dried and concentrated. Column chromatography on silica (20-30% EtOAc in hexane) provided the title compound (0.32 g, 50%) as a viscous oil. MS calculated for C26H38F3N3O2: (M+H)+ 482. found 482.3.
