Procedure

[6-(4-nitrophenoxy)pyridin-3-yl]methanol (6.1 g, 24.8 mmol) was dissolved in dichloromethane (150 mL), and to the resulting solution was added triethylamine (4.15 mL, 29.8 mmol) under ice cooling. To the resulting solution was added dropwise methanesulfonic acid chloride (2.11 mL, 27.3 mmol), and then stirred under a nitrogen atmosphere for 30 minutes at 0° C. The reaction solution was washed with a saturated sodium bicarbonate solution and brine. The organic layer was dried over anhydrous magnesium sulfate, and evaporated. To the residue was added a mixed solvent (50 mL) of n-hexane:ethyl acetate=1:1. The precipitated crystals were removed by suction filtration, to thereby yield 7.9 g of the title compound.
