7-Chloro-1,8-naphthyridin-2-amine → HCID 13983407, compound
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 7-Chloro-1,8-naphthyridin-2-amine | HCID 85199 | — |
| Reactant | 4-Thiazolecarboxylic acid | HCID 304271 | — |
| Solvent | Water | HCID 962 | — |
| Product | HCID 13983407 | HCID 13983407 | 77.2% |
Reaction Steps
The procedure is similar to that described in Example 2, but starting with 4-thiazolecarboxylic acid (4.8 g), N,N'-carbonyldiimidazole (7.5 g) and 2-amino-7-chloro-1,8-naphthyridine (4.8 g). The product obtained by precipitation in water is purified by recrystallization in dimethylformamide (350 cc). N-(7-Chloro-1,8-naphthyridin-2-yl)-4-thiazolecarboxamide (6 g), m.p. 325° C., is thereby obtained.
