Reaction Steps

Under ice cooling, methanesulfonyl chloride (4.2 mL, 54 mmol) was added to a solution of N-(2-t-butoxycarbonylaminophenyl)-5-hydroxymethylpyridine-2-carboxylic acid amide (Reference Compound No. 3-1, 16 g, 45 mmol) and triethylamine (16 mL, 110 mmol) in dichloromethane (150 mL), and then the reaction mixture was stirred for 1 hour. Water (400 mL) was added thereto, and then the whole was extracted with ethyl acetate (500 mL) five times. The organic layer was washed with water (500 mL), dried over anhydrous magnesium sulfate, and then the solvent was evaporated under reduced pressure. The resulting solid was collected by filtration with hexane (80 mL) and ethyl acetate (20 mL) to give 18 g of the title reference compound as a white solid. (Yield 94%)
