The resulting mixture was heated at 120° C. under microwave irradiation for 2 h. The reaction mixture was cooled, diluted with water (40 mL) to afford a solid. The solid was isolated by filtration then purified by chromatography on silica using hexanes/ethyl acetate (10:0 to 0:10) as eluent to afford the title compound (0.098 g, 51%) as a light brown solid.
