Reaction Steps

The procedure is analogous to that described in Example 1, but starting with 4-methoxybenzoic acid (6.1 g), N,N'-carbonyldiimidazole (6.5 g) and 2-amino-7-anilino-1,8-naphthyridine (7 g). The product obtained by precipitation in water (12 g) is dissolved in boiling ethanol (140 cc). After cooling for 1 hour at 4° C., the crystallized solid is separated by filtration, washed with ethanol (10 cc), and dried at 45° C. under reduced pressure (0.07 kPa). N-(7-Anilino-1,8-naphthyridin-2-yl)-4-methoxybenzamide (4.5 g), m.p. 245° C., is obtained.
