Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Hydroxy-3-methoxybenzonitrile | HCID 78135 | — |
| Reactant | 3-Ethoxy-4-hydroxybenzonitrile | HCID 3800659 | — |
| Product | 3,4-Dihydroxybenzonitrile | HCID 87065 | 79% |
Reaction Steps
The preparation was carried out according to the process of Example 2a except that 3-ethoxy-4-hydroxybenzonitrile was used as the starting material instead of 3-methoxy-4-hydroxybenzonitrile. 3,4-Dihydroxybenzonitrile was obtained as a white solid with a yield of 79% and a purity of greater than 98% as indicated by HPLC analysis.
