Reaction Steps

Methanesulfonyl chloride (160 μL, 2.05 mmol) was added dropwise to a solution of (3-phenylbenzofuran-2-yl)methanol (367 mg, 1.64 mmol) and DIPEA (343 μL, 1.97 mmol) in anhydrous DCM (10 mL) at 0° C. Stirring at 0° C. was continued for 15 min, then the mixture slowly warmed to RT. After 2 h at RT, additional amounts of methanesulfonyl chloride (80 μL, 1.03 mmol) and DIPEA (172 μL, 0.99 mmol) were added and stirring continued for 1.5 h. The reaction mixture was diluted with DCM and the organic fraction washed with water, dried (Na2SO4) and concentrated in vacuo affording the title compound as an oil (443 mg, 89%). 1H NMR (DMSO-d6, 400 MHz): δ 7.71-7.64 (2H, m), 7.62-7.56 (4H, m), 7.52-7.41 (2H, m), 7.37-7.32 (1H, m), 4.98 (2H, s), 3.89 (3H, s)
