Reaction Steps

To a solution of (3S)-1-Boc-3-[(4,4-dimethylcyclohexyl)(3-hydroxy-2,2-dimethylpropanoyl)amino]pyrrolidine (210 mg, 0.53 mmol) prepared in Step B of Example A8 in THF was added dropwise borane-methylsulfide complex (in THF, 2.0M, 0.4 ml, 0.8 mmol), and stirred at 80° C. for 3 h. After the reaction finished, the solvent was concentrated in vacuo, water added, extracted with EtOAc. The organic layer was dried over MgSO4, concentrated in vacuo, and purified by column chromatography (eluent: DCM/MeOH=9/1) to give the title compound (140 mg, 75%).
