Acetyl chloride → HCID 86584269, compound

Participants

Reaction Steps

Under an inert atmosphere, acetyl chloride (29.1 ml, 0.385 mol) is slowly added to a suspension of aluminum chloride (51.2 g, 0.385 mol) stirred in 1,2-dichloroethane (750 ml). After stirring at room temperature for 1 hour a yellow solution is obtained. The solution is cooled in an ice bath and N,N-dimethyl-2-(2′,3′,5′,6′-tetrafluoroanilino)phenylacetamide (40 g, 0.123 mol) is added. The reaction is allowed to warm to room temperature and then warmed to 80° for 0.5 hours. The reaction is poured over ice and extracted with EtOAc (2×750 ml). The organic extract is washed with water (750 ml), saturated NaHCO3 solution (500 ml) and brine (500 ml). Evaporation on a rotovap and trituration with Et2O gives N,N-dimethyl-5-acetyl-2-(2′,3′,5′,6′-tetrafluoroanilino)phenylacetamide as a white solid, m.p. 112-114°.
