The mixture was heated as reflux and after about 5 minutes a solid precipitate formed. Refluxing was continued for 2 hours, then the hot reaction mixture was filtered to collect the precipitate. The precipitate was washed with two 50 ml portions of acetone, then air dried to give 28.9 g of the product as a white solid, mp 189°-190° C. (dec.).
