Reaction Conditions

Reaction Steps

The procedure is analogous to that described in Example 11, but starting with 3-bromobenzoic acid (2.2 g), N,N'-carbonyldiimidazole (1.8 g) and 2-amino-7-(3-bromophenyl)-1,8-naphthyridine (2.4 g). The product obtained by precipitation in water (3.1 g; m.p. approximately 140° C.) is dissolved in boiling propanol (100 cc). After cooling for 3 hours at 4° C., the crystallized solid is separated by filtration, washed with propanol (2×10 cc) and dried at 40° C. under reduced pressure (0.07 kPa). N-[7-(3-Bromophenyl)-1,8-naphthyridin-2-yl]-3-bromobenzamide (2.2 g), m.p. 144°-146° C., is obtained.
