Methyl iodide → HCID 13141014, compound

Participants

Reaction Steps

To a solution of cyclopropyl-carbamic acid benzyl ester (11.8 g) and methyl iodide (excess) in THF (80 mL) and DM (20 mL) at 0° C. was added NaH (2.20 g, 91.6 mmol) and the resulting mixture was warmed to room temperature and stirred overnight. The reaction was then quenched at 0° C. by sat NaHCO3. The separated aqueous phase was extracted several times with EtOAc. The combined extracts were dried over Na2SO4, filtered and concentrated. The residue was purified by chromatography (5% to 20% EtOAc/hexanes) to give cyclopropyl-methyl-carbamic acid benzyl ester (11.32 g, 91%).
