Reaction Steps
The procedure is analogous to that described in Example 1 below but starting with 4-trifluoromethylbenzoic acid (2.7 g), N,N'-carbonyldiimidazole (2.3 g) and 2-amino-7-(4-methoxyphenyl)-1,8-naphthyridine (2.5 g). The product obtained by precipitation in water (3.3 g; m.p. 144°-146° C.) is dissolved in boiling acetonitrile (100 cc). After cooling for 3 hours at 4° C., the crystallized solid is separated by filtration, washed with acetonitrile (2×10 cc) and dried at 40° C. under reduced pressure (0.07 kPa). N-[7-(4-Methoxyphenyl)-1,8-naphthyridin-2-yl]-4-trifluoromethylbenzamide (2.4 g), m.p. 148° C., is obtained.
