Participants

Reaction Steps

To a solution of (3S)-1-Boc-3-[(4,4-dimethylcyclohexyl)(3-hydroxy-2,2-dimethylpropanoyl)amino]pyrrolidine (800 mg, 2.02 mmol) prepared in Step B of Example A8 in THF was added NaH (73 mg, 3.03 mmol) and iodomethane (430 mg, 3.03 mmol) at 0° C., and the solution was stirred at rt for 2 h. After the reaction finished, the solution was concentrated in vacuo, extracted with 1N-HCl and EtOAc. The organic layer was washed with brine, dried over MgSO4, and concentrated in vacuo. The residue was purified by column chromatography (eluent: EtOAc/Hex=1/2) to give the title compound (784 mg, 94.6%).
