Procedure

To a 0° solution of 15 g of 2-(aminomethyl)pyridine, 15.44 g of triethylamine and 150 ml of methylene chloride is added 17.48 g of methanesulfonyl chloride in 100 ml of methylene chloride. The mixture is stirred at 0° C. for 1 hour followed by stirring at room temperature for 3 hours. The reaction is poured into saturated sodium bicarbonate and extracted with methylene chloride. The combined extracts are washed with saturated sodium chloride and concentrated in vacuo. The residue is purified by chromatography (silica gel: 10% methyl alcohol/ethyl acetate) to give 19.84 g of the desired product.
