Procedure

To a solution of ethyl [(4S,6S)-6-(3,5-difluorophenyl)-4-hydroxy-3,3-dimethyl-2-oxopiperidin-1-yl]acetate from Step C (64 mg, 187 mmol) in THF (1 mL) and H2O (0.5 mL) was added LiOH monohydrate (14 mg, 334 mmol) and the resulting mixture was stirred at ambient temperature for 1 h. The reaction mixture was quenched with 1 N HCl (0.40 mL, 400 mmol), concentrated in vacuo and dried to afford the title compound. MS: m/z=314 (M+1).
