Butanol (5 mL) was added to the reaction mixture, which was then heated overnight at 100° C. in a sealed vial. The reaction mixture was cooled, diluted with water and extracted twice with ethyl acetate. The combined organic layers were washed with brine, dried (Na2SO4) and concentrated to give an orange solid. Flash chromatography on silica (20 g), eluting with 15-60% ethyl acetate-hexane, gave the title compound as a yellow solid (333 mg, 1.51 mmol, 45%). LC-MS (1) Rt=1.68 min; m/z (ES+) 221/223.
