Procedure

To a solution of (3S)-1-Boc-3-[(4,4-dimethylcyclohexyl)(2,2-dimethyl-3-oxopropanoyl)amino]pyrrolidine (250 mg, 0.63 mmol) prepared in Step A of Example C3 in THF was slowly added dropwise methylmagnesium bromide (in diethylether, 3.0M, 0.25 ml, 0.76 mmol) at 0° C., and the solution was stirred at rt for 2 h. After the reaction finished, to the solution was added 1N-HCl at 0° C., and extracted with EtOAc. The organic layer was dried over MgSO4, concentrated in vacuo, and purified by column chromatography (eluent: EtOAc/Hex=1/2) to give the title compound (238 mg, 92%).
