Reaction Conditions

Reaction Steps

The procedure is similar to that described in Example 1, but starting with 4-methoxybenzoic acid (10.2 g), N,N'-carbonyldiimidazole (10.8 g) and 2-amino-7-bromo-1,8-naphthyridine (11.2 g). The product produced by precipitation in water (9.8 g; m.p. 220° C.) is dissolved in boiling acetonitrile (1000 cc). After 2 hours' cooling at 4° C., the crystallised solid is separated by filtration, washed with acetonitrile (2×10 cc) and dried at 40° C. under reduced pressure (0.067 kPa). N-(7-bromo-1,8-naphthyridin-2-yl)-4-methoxybenzamide (8.3 g) is produced, m.p. 221° C.
