反応手順

To a stirred solution of (2-chloropyridin-4-yl)methanol (0.500 g, 3.496 mmol) in dichloromethane (15 mL), triethylamine (0.424 g, 4.195 mmol) and methanesulfonylchloride (0.440 g, 3.846 mmol) were added at 0° C. and stirred at room temperature for 2-3 h. The reaction was quenched with water and extracted with dichloromethane. The organic layer was concentrated in vacuo to give (2-chloropyridin-4-yl)methyl methanesulfonate (0.530 g, 68%); MS: 221.9 (M+1).
