Acetyl chloride → Methyl 2-(4-acetamidomethylphenyl)-2-methylpropionate

Participants

Reaction Steps

To a solution of methyl 2-(4-aminomethylphenyl)-2-methylpropionate (29.4 g) and triethylamine (23.8 ml) indichloroethane (300 ml) was added dropwise acetyl chloride (11.1 ml) at 5° C. over 30 min. The mixture was stirred at room temperature for 30 min. The reaction mixture was poured into water and the organic layer was separated. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated and the obtained residue was purified by silica gel column chromatography (developing solvent; ethyl acetate:hexane=3:1, ethyl acetate) to give the title compound (23.47 g) as a pale-yellow oil.
