Reaction Steps

The procedure is analogous to that described in Example 1, but starting with 4-trifluoromethylbenzoic acid (10 g), N,N'-carbonyldiimidazole (8.4 g) and 2-amino-7-chloro-1,8-naphthyridine (5.9 g). The product obtained by precipitation in water (11.5 g; m.p. 236° C.) is dissolved in boiling acetonitrile (250 cc). After cooling for 4 hours at 4° C., the crystallized solid is separated by filtration, washed with acetonitrile (2×20 cc) and dried at 45° C. under reduced pressure (0.07 kPa). N-(7-Chloro-1,8-naphthyridin-2-yl)-4-trifluoromethylbenzamide (9 g), m.p. 236° C., is obtained.
