Reaction Steps
In 1600 ml of acetic acid were dissolved 400 g of 2-(1,1-dimethylethyl)-4-methoxyphenol, 360 g of 40% glyoxal solution and 20 ml of 36% hydrochloric acid and the solution was heated at 120° C. with stirring for 4 hours. The reaction mixture was concentrated under reduced pressure and allowed to stand overnight. The resultant solid residue was washed with diethyl ether to give 105 g of 7-(1,1-dimethyethyl)-5-methoxy-2(3H)-benzofuranone as a light red solid.
