Reaction Steps

A mixture of 4-hydroxyphenylacetic acid (20.0 g, 131 mmol) and 3,5-dimethylaniline (15.9 g, 131 mmol) in xylene (100 mL) was stirred for three days at 160° C. with a Dean Stark trap. The mixture was cooled to room temperature and filtered. The solid product obtained was washed with hexane (200 mL), 10% sodium bicarbonate solution (250 mL), water (200 mL), 10% hydrochloric acid (200 mL), and then water (200 mL).
