After the addition was complete, stirring was continued for 18 hours. The solid was isolated by filtration, washed with diethyl ether, and dried at room temperature under vacuum. Yield 0.43 g (15%), m.p. 90°-93° C. Infrared, nuclear magnetic resonance, and mass spectra were in agreement with that expected for the structural formula.
