The reaction mixture was heated at reflux for 1.5 hours. To the reaction mixture was added 1N hydrochloric acid, and the mixture was extracted with chloroform. The organic layer was dried over anhydrous magnesium sulfate, and concentrated in vacuo to give the title compound (247.7 mg, quantitative yield).
