Reaction Conditions

Reaction Steps

The procedure is analogous to that described in Example 1, but starting with 3-bromobenzoic acid (6 g), N,N'-carbonyldiimidazole (4.9 g) and 2-amino-7-phenoxy-1,8-naphthyridine (5.9 g). The product obtained by precipitation in water (9.8 g; m.p. 188°-192° C.) is dissolved in acetonitrile (300 cc). After cooling for 1 hour at 4° C., the crystallized solid is separated by filtration, washed with acetonitrile (3×10 cc) and dried at 40° C. under reduced pressure (0.07 kPa). N-(7-Phenoxy-1,8-naphthyridin-2-yl)-3-bromobenzamide (5.4 g), m.p. 194° C., is obtained.
