The reaction mixture became viscous, and methanol (100 ml) was added. The reaction mixture was allowed to come to room temperature and to stir for about 11/2 hours. The reaction mixture was cooled in an ice-water bath and the product removed by filtration. The precipiate was dried under vacuum to give 8.9 g of the above-identified product as an off-white solid, melting point 153°-156° C.
