The mixture was heated to 150° C. for 24 hours under an atmosphere of nitrogen. The reaction was diluted with EtOAc, washed with sat. NH4OAc and brine, dried over sodium sulfate, concentrated and purified by silica gel chromatography (Hexanes:DCM) and the solvent removed to afford the title compound. LC-MS (IE, m/z): 189 [M+1]+.
