Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 4-Hydroxy-3-methoxybenzonitrile | HCID 78135 | — |
| Reactant | Benzo-1,3-dioxole-5-carbonitrile | HCID 78136 | — |
| Product | 3,4-Dihydroxybenzonitrile | HCID 87065 | 94% |
Reaction Steps
The preparation was carried out according to the process of Example 2a except that 3,4-(methylenedioxy)benzonitrile was used as the starting material instead of 3-methoxy-4-hydroxybenzonitrile to form the reaction mixture. 3,4-Dihydroxybenzonitrile was obtained as a pale brown solid with a yield of 94% and a purity of greater than 97% as indicated by HPLC analysis.
