Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 1H-Indazol-5-amine | HCID 88012 | — |
| Reactant | 4-Chloro-6-nitroquinazoline | HCID 11356257 | — |
| Product | HCID 23366763 | HCID 23366763 | 68% |
Reaction Steps
Using an analogous procedure to that described in Example 1, 4-chloro-6-nitroquinazoline was reacted with 5-amino-1H-indazole to give in turn 4-(1H-indazol-5-ylamino)-6-nitroquinazoline hydrochloride in 68% yield, m.p. 289°-291° C., and the free base in quantitative yield.
