The reaction mixture was stirred for 6 hours at room temperature, followed by addition of H2O, and then subjected to celite filtration. Evaporation of the resultant mixture under diminished pressure gave a white solid. Recrystallization of this solid from chloroform/hexane gave a colorless needle-like crystal (1.346 g, 100%, m.p. 26 to 28° C.).
