Participants

Reaction Steps

5-tert-Butylsalicylaldehyde (163 g) was dissolved in 1.5 liters of acetonitrile, 252.5 g of anhydrous potassium carbonate was added and 84.6 g of chloroacetone was dropped into the mixture with stirring at room temperature. After completion of the dropping, the reaction mixture was stirred for 8 hours and then insoluble matters were filtered off. The filtrate was concentrated in vacuo and the residue was dissolved in ethyl acetate followed by washing with water twice. The ethyl acetate layer was dried over anhydrous magnesium sulfate and concentrated in vacuo. The residue was crystallized by adding isopropyl ether thereto followed by filtering to give 120.5 g of crystals. M.p. 99°-101° C.
