The mixture is heated to reflux for 1.5 hours and cooled and diluted with 40 mL of diethyl ether. The resulting solid is filtered and dissolved in a mixture of dichloromethane and saturated sodium bicarbonate solution. The organics are separated, dried over sodium sulfate, filtered and concentrated to provide 0.565 g of the titled compound. MS (m/e) 311.1 (M+1)
