Procedure

Pyridin-4-ylmethanol (4.0 g, 37 mmol) was dissolved in dichloromethane (50 mL), and triethylamine (11.21 g, 111 mmol) was added to the reaction mixture. The solution was cooled to 0° C. and methanesulfonyl chloride (MsCl) (6.3 g, 55.5 mmol) was added slowly. After the addition was complete, the reaction was stirred at 0° C. for 15 min and then stirred at room temperature for 2 hours. Water was slowly added and the solution was extracted with dichloromethane. The organic layer was washed with brine, and dried over sodium sulfate and concentrated in vacuo. The residue was dissolved in methanol, and activated charcoal was added. After the mixture was stirred for 1 hour the mixture was filtered through a plug of celite and concentrated in vacuo to afford pyridine-4-ylmethyl methanesulfonate (49).
