Reaction Steps

Ethyl 7-(4-fluorophenyl)-4,7-dioxoheptanoate (2.00 g, 7.1 mmol) and 2-methyl-1H-imidazole (7.0 g, 86 mmol) were taken up into DMSO (4 mL). The mixture was heated to 180° C. under microwave for 72 min. Water (100 mL) was added and the mixture was extracted with ethyl acetate (50 mL×3). The combined organic layers were washed with brine (40 mL), dried over Na2SO4, filtered, concentrated and purified by silica gel column chromatography (DCM to DCM:MeOH=25:1) to afford the title compound as a dark brown solid (660 mg, yield 25%).
