| Reactant | HCID 178469716 | HCID 178469716 | — |
| Product | 2,7-Diethyl-4-oxo-4,7-dihydrothieno[2,3-b]pyridine-5-carboxylic acid | HCID 20363723 | — |
Reaction Steps
In a manner similar to that described in Example 13, ethyl 2-ethyl-4-hydroxythieno[2,3-b]pyridine-5-carboxylate is reacted with ethyl iodide to obtain 2,7-diethyl-4,7-dihydro-4-oxothieno-[2,3-b]pyridine-5-carboxylic acid. Recrystallization from methanol gives colorless prisms melting at 197°-198° C.
