Reaction Steps
The compound 20 (138 g, 0.596 mol), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (148 g, 0.775 mol), and 1-hydroxybenzotriazole (100 g, 0.656 mol) were dissolved in methylformamide (970 ml), and 4-fluorobenzylamine (79 ml, 0.715 mol) was added. After the reaction solution was stirred at room temperature for 9 hours, water (2000 ml) was added, and crystals were collected by filtration, followed by washing with ether. 5-Bromo-N-(4-fluorobenzyl)-4-hydroxy-6-methylnicotinamide 21 (156 g, 77%) was obtained as a colorless crystal.
