temperature, the ampoule was opened, and the reaction mixture
was treated with diluted (10%) hydrochloric acid. The water
layer was separated, neutralized with 10% solution of sodium hy-
droxide, and extracted with dichloromethane. The organic layer
was filtered, and the solvent was distilled off. The residue was
distilled in a vacuum or recrystallized from hexane (Table 3).
