Methyl iodide → 3-Ethyl-1-(2-methoxy-ethyl)-3-(3-benzyloxy-phenyl)-azepan-2-one

Participants

Reaction Steps

Sodium hydride (0.017 g, 0.425 mmol) was added to a solution of 3-ethyl-1-(2-hydroxy-ethyl)-3-(3-benzyloxyphenyl)-azepan-2-one, as described in Example 54, Step C, (0.12 g, 0.327 mmol) in DMF (5 mL) at 0° C. with stirring. After 20 min CH3I (0.041 mL, 0.653 mmol) was added and stirring was continued at room temperature for 16 h. The reaction was quenched with H2O and the solvents removed in vacuo. The residue was partitioned between EtOAc and saturated NaHCO3 solution. The organic layer was separated, washed with brine and dried (MgSO4). Filtration and concentration gave the title compound.
