Procedure
To a solution of N-[2-(3-acetyl-5-chloro-2-methoxy-6-methylphenyl)-2-hydroxyethyl]-2-chloroacetamide (170 mg, 0.50 mmol) (single enantiomer from step 3) in tetrahydrofuran (4 mL) cooled at 0° C., a mixture of sodium hydride (60% dispersion in mineral oil; 39 mg, 1.0 mmol) was added and stirred for 1 hour. The reaction was quenched with water and extracted with ethyl acetate. The combined extracts were washed with brine, dried over sodium sulfate, and concentrated to give the crude residue as a single enantiomer, 61 mg, 41%. LCMS calculated for C14H17ClNO4 (M+H)+: m/z=298.1; found: 298.1.
