| Reactant | Thiopyrano[3,2-b]indol-4(5H)-one | HCID 20326608 | — |
| Product | 5-(2-Nitrophenyl)thiopyrano[3,2-b]indol-4(5H)-one | HCID 20326622 | — |
Reaction Steps
By the same method as described in Example 7, 8.9 g of thiopyrano [3,2-b]-indol-4-(5H)-one is alkylated with o-fluoronitrobenzene, except the reaction is stirred for 40 hours at 95°C. The yield of product is 9.2 g, mp 207°-208°C after recrystallization from ether-hexane.
