Reaction Steps
The procedure is similar to that described in Example 1, but starting with 4-methoxybenzoic acid (4.6 g), N,N'-carbonyldiimidazole (4.9 g) and 2-amino-7-chloro-1,8-naphthyridine (3.6 g). The product produced by precipitation in water (4.3 g; m.p. 208° C.) is dissolved in boiling acetonitrile (660 cc). After 3 hours' cooling at 4° C., the crystallised solid is separated by filtration, washed with acetonitrile (3×20 cc) and dried at 50° C. under reduced pressure (0.067 kPa). N-(7-chloro-1,8-naphthyridin-2-yl)-4-methoxybenzamide (3.5 g) is produced, m.p. 208° C.
