Phenylacetyl chloride → N-(4-methylphenyl)-2-phenylacetamide

Participants

Reaction Steps

1.0 g (9.3 mmol) of 4-methylaniline is dissolved in toluene (10 ml) at 0° C., under a nitrogen atmosphere. A solution of phenylacetyl chloride (1.25 ml, 9.4 mmol) in 20 ml of toluene is added dropwise to the medium. The reaction mixture is stirred at room temperature for 2 h and the medium is then hydrolyzed with cold sodium hydrogen carbonate solution. The two-phase system is stirred vigorously for 30 min and the organic phase is then collected. The aqueous phase is extracted with ethyl acetate (twice). The organic phase is dried over MgSO4 and then evaporated. The residue obtained is purified by chromatography on a column of silica (3/7 EtOAc/PE) to give 1.9 g (92%) of compound 47.
