To a stirred solution of tert-butyl 3-hydroxypyrrolidine-1-carboxylate (0.5 g, 2.67 mmol) in THF (20 mL) at 0° C. was added NaH (60%, 0.077 g, 3.2 mmol) and the mixture was stirred for 15 min. Methyl iodide (0.2 mL, 3.2 mmol) was slowly added and the reaction was stirred for 18 h at ambient temperature. The reaction was quenched with water (5 mL) and extracted with DCM (3×10 mL). The combined organic extracts were washed with water (6 mL), brine (8 mL), dried over Na2SO4 and concentrated in vacuo. The resulting residue was purified by FCC eluting with DCM to afford the title compound.
