4-Chlorobenzoyl chloride → HCID 14097617, compound

Participants

Reaction Steps

Methyl 4-(2-aminoethoxy)benzoate (19.5 g) and 13.8 g of anhydrous potassium carbonate were added to 200 ml of chloroform and the mixture was stirred with cooling. p-Chlorobenzoyl chloride (17.5 g) was dropped thereinto at 10°-20° C. The mixture was stirred for 3 hours. The reaction solution was washed with water, the chloroform layer was dried with anhydrous magnesium sulphate, concentrated in vacuo, the residue was crystallised with n-hexane, and the crystals were recrystallised with ethyl acetate/n-hexane to give 25.4 g of crystals of m.p. 125°-127° C., yield 76%.
