The reaction mixture was then allowed to warm to ambient temperature and stirring was continued for 20 h. Sodium sulfate decahydrate (6 g) was then added to quench the reaction and the resultant reaction mixture was filtered then the filtrate was then evaporated under reduced pressure. The resultant oil was purified by flash chromatography (silica, 50 g column, ISCO, 0-10% methanol in DCM) to afford the title compound as an orange oil (96 mg, 5%). 1H NMR (DMSO-D6, 400 MHz): 7.18 (s, 2H), 3.68 (s, 2H), 2.73-2.64 (m, 4H), 2.52-2.48 (m, 2H), 1.19-1.11 (m, 6H).
