Procedure

To a 386 mg (1.84 mmol) sample of 3-(trans-1-methyl-4-hydroxymethyl-2(S)-pyrrolidinylmethoxy)pyridine (from Example 48a above) dissolved in 12 mL of methylene chloride were added 262 μL (3.38 mmol) of methanesulfonyl chloride, 470 μL of triethylamine and a catalytic amount of DMAP, and the reaction mixture was stirred for 5 hours at room temperature. The reaction was quenched with water, the product extracted from the mixture, the solvent removed, and the product purified by column chromatography on silica gel, eluting with 20:1 chloroform:methanol to afford 320 mg of the title compound.
