To a solution of tert-butyl [(2R)-2-hydroxypropyl]carbamate (0.4 g, 2.28 mmol) in THF (5 mL), sodium hydride (0.06 g, 2.51 mmol) was added at 0° C. The resulting solution was stirred for 30 minutes at that temperature and then methyl iodide (0.14 mL, 2.28 mmol) was added. The reaction was warmed to room temperature slowly and allowed to stir for an additional two hours. The reaction was quenched by adding water and extracted with ethyl acetate. The extract was washed with sodium bicarbonate solution, water and brine. It was dried over magnesium sulfate and concentrated. The desired product was obtained as clear oil (0.31 g) and it did not need any further purification.
