Reaction Conditions

Reaction Steps

The procedure is similar to that described in Example 1, but starting with 4-methoxybenzoic acid (10.2 g), N,N'-carbonyldiimidazole (10.9 g) and 2-amino-7-(2-methoxyphenoxy)-1,8-naphthyridine (13.4 g). The product produced by precipitation in water (18 g; m.p. 167° C.) is dissolved in boiling ethanol (400 cc). After 2 hours' cooling at 4° C., the crystallised solid is separated by filtration, washed with ethanol (2×10 cc) and dried at 45° C. under reduced pressure (0.067 kPa). N-[7-(2-methoxyphenoxy)-1,8-naphthyridin-2-yl]-4-methoxybenzamide (14 g) is produced, m.p. 168°-170° C.
