Reaction Conditions

Reaction Steps

To a stirred solution of 3-nitroaniline (1 g. 7.2 mmol.) in acetic acid (10 ml), activated silferc (1.15 g. ferric chloride 7.2 mmol) was added under nitrogen atmosphere. The reaction mixture was stirred for 5 minutes and methyl vinyl ketone (MVK) (0.55 g, 7.9 mmol) was added slowly over a period of 15 minutes. The reaction mixture was heated to 70° C. and maintained between 70-75° C. for one hour. Anhydrous zinc chloride (1.0 g. 7.2 mmol) was added and the reaction was further refluxed for two hours. The reaction mixture was cooled, filtered, basified with 10% NaOH solution, extracted with ethyl acetate (3×20 ml), dried over Na2SO4 and evaporated to give the product; Yield 64%.
