Reaction Steps

The procedure is analogous to that described in Example 1, but starting with 3,4,5-trimethoxybenzoic acid (17 g), N,N'-carbonyldiimidazole (13 g) and 2-amino-7-chloro-1,8-naphthyridine (8.9 g). The product obtained by precipitation in water (10.3 g; m.p. 90° C.) is dissolved in boiling ethanol (500 cc). After cooling for 4 hours at 4° C., the crystallized solid is separated by filtration, washed with ethanol (20 cc) and dried at 40° C. under reduced pressure (0.07 kPa). N-(7-Chloro-1,8-naphthyridin-2-yl)-3,4,5-trimethoxybenzamide (8.2 g), m.p. 210° C., is obtained.
