Reaction Steps

Ethylsulfonyl chloride (233 uL, 2.4 mmol) was added to a stirred solution of 3-bromo-4-(cyclopropylmethoxy)aniline (520 mg, 2.2 mmol) and pyridine (520 uL, 6.5 mmol) in DCM (4 mL) at 0° C. under nitrogen. After the mixture was allowed to warm to rt and stir for 12 h, it was treated with 1N HCl (15 mL) and extracted with DCM (3×15 mL); the combined organic extracts were washed with saturated bicarbonate solution (aq), dried over sodium sulfate, filtered and concentrated in vacuo. The resulting residue was purified by silica gel column chromatography using a gradient of EtOAc (10 to 100%) in hexanes to afford the title compound (711 mg, 98%) as a yellow solid. LCMS (M+H)+=335.
