Reaction Steps
The procedure is analogous to that described in Example 1, but starting with phenylacetic acid (10.9 g), N,N'-carbonyldiimidazole (13 g) and 2-amino-7-chloro-1,8-naphthyridine (10.8 g). The product obtained by precipitation in water (13.5 g; m.p. 184° C.) is dissolved in boiling acetonitrile (210 cc). After cooling for 1 hour at 4° C., the crystallized solid is separated by filtration, washed with acetonitrile (10 cc) and dried at 45° C. under reduced pressure (0.07 kPa). N-(7-Chloro-1,8-naphthyridin-2-yl)phenylacetamide (11.3 g), m.p. 187° C., is obtained.
