The solution was cooled to 5° C. and acetic anhydride, 11.22 grams, (0.11 mole) was added slowly. The mixture was stirred for 2 hours and allowed to come to room temperature. The reaction mixture was mixed with a quantity of water, allowed to stand until the water layer separated, and the water layer was discarded. The toluene solution was evaporated to leave 21.4 grams of a solid residue, 96% of theory. The material melted at 63-65° C.
