The reaction mixture was heated at 100° C. for 4 h. The reaction mixture was then diluted with water (20 ml) and extracted with diethyl ether (3×10 ml). The combined organic extracts were dried (MgSO4), filtered and concentrated in vacuo to give the title compound as an oil which was not purified further (500 mg, 89%).
