Versuchsvorschrift

A solution of 20 (30.9 g, 0.187 mole) in of acetic anhydride (200 ml) heated at reflux for 1.5 hours, cooled to room temperature and poured with vigorous stirring into 2N aqueous Na2CO3 (2 L). Overnight refrigeration gave a solid which was collected, washed with water, and dried to give 25.6 grams (93%) of 21 m.p. 48°-50°.
