HCID 4572422-(4-chlorophenyl)-1-(4-methoxyphenyl)ethanone

Procedure

Anisole (13.9 g, 0.13 mol) is added to a stirred solution of 4-chlorophenylacetic acid (20.0 g, 0.12 mol) in trifluoroacetic anhydride (16.5 ml, 0.12 mol). The mixture is stirred in room temperature for 24 h. Ice water is added and the crystallized product is collected on a sinter and washed with water. The product is recrystallized from ethanol. The yield is 20.4 g, 67%.
