Participants

Reaction Steps

A solution of 1-(4′-chloro-2-methoxybiphenyl-3-yl)-N-(4-fluorobenzyl)methanamine (590 mg, 1.684 mmol, 1.0 eq) in dry DCM under nitrogen at 0° C. and treated slowly with triethylamine (492 mg, 4.8 mmol, 3 eq). The reaction mixture was stirred for 10 minutes and treated with a solution of 3,5-dichloro-2-hydroxybenzene-1-sulfonyl chloride (527 mg, 2.018 mmol, 1.2 eq) dissolved in DCM. The resulting mixture was stirred for 12 h at ambient temperature and concentrated under reduced pressure. The residue was further diluted with water and extracted with ethyl acetate. The organic layer was dried under anhydrous Na2SO4 and concentrated. The residue was purified by flash column chromatography on silica gel (60-120) eluting with 15-20% ethyl acetate/hexane to afford the title compound (0.400 g, 50%). 1H NMR (400 MHz, DMSO-d6) δ 3.32 (s, 3H), 4.52-4.53 (d, 4H), 7.04-7.08 (m, 3H), 7.17-7.24 (m, 4H), 7.43-7.52 (m, 5H), 7.77 (s, 1H). MS (ESI): 577.8 (M−H)−.
