実験手順
To a mixture of 4-chloro-N-ethyl-3′,5′-difluoro-6-(1-hydroxyethyl)-3-methylbiphenyl-2-carboxamide (185 mg, 0.523 mmol) in methylene chloride (3 mL) was added N,N-diisopropylethylamine (0.18 mL, 1.0 mmol), followed by methanesulfonyl chloride (0.061 mL, 0.78 mmol). The reaction was stirred at rt for 10 min, quenched by pouring onto iced water, and extracted with dichloromethane. The combined organic layers were washed with aq. sodium bicarbonate, dried over magnesium sulfate, and evaporated to dry. The residue was used directly in next step (0.226 g, 100%). LCMS calculated for C19H21ClF2NO4S (M+H)+: m/z=432.1; Found: 432.1.
