Reaction Steps

To a stirred solution of methyl 2,2-dimethyl-5-oxo-5-[3-(trifluoromethyl)phenyl]pentanoate from Step A (45.0 mg, 0.149 mmol) and glycine (99.0 mg, 1.32 mmol) in MeOH (2 mL) and acetic acid (0.045 mL) was added sodium cyanoborohydride (50.0 mg, 0.794 mmol). The reaction mixture was heated to reflux for 18 h. To the resulting mixture was added xylenes (3 mL) and heated to 140° C. for 4 h. The solvent was removed in vacuo and the crude solid dissolved in DMSO (1 mL). The crude product was purified by HPLC using a reversed phase C18 column and eluting with a gradient of H2O:CH3CN:CF3CO2H—90:10:0.1 to 5:95:0.1. Lyophilization provided the title compound. MS: m/z=330 (M+1).
