Reaction Steps
A mixture of the bromide from Step 1 (0.543 g), 4-fluorophenylboronic acid (0.31 g), tetrakis(triphenylphosphine) palladium (0) (0.2 g), 2M aqueous sodium carbonate (2.2 mL) and toluene (10 mL) was refluxed under N2 for 1.5 hours. The mixture was cooled, poured into water (75 mL) and extracted with ethyl actetate (2×25 mL). The extracts were dried over Na2SO4, filtered and concentrated. Flash column chromatography, eluting with 40% ethyl acetate-isohexane, gave 1-(dimethylaminosulfonyl)-4-(4-fluorophenyl)imidazole (0.417 g, 72%) as a yellow solid. MS (ES+) 270 ([MH]+).
