To a solution of benzyl [(1R)-2-hydroxy-1-methylethyl]carbamate (0.5 g, 2.38 mmol) in acetonitrile (20 mL), silver oxide (3.8 g, 13.09 mmol) is added followed by the addition of methyl iodide (1.94 mL, 23.8 mmol). The resultant mixture was stirred overnight at room temperature. The insoluble salt was filtered off and the filtrate was concentrated. The residue was flashed using silica and Ethyl acetate/hexanes system as eluent to give the desired product as clear oil (0.38 g).
