Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | 2-Acetyl-5-methylthiophene | HCID 83655 | — |
| Reactant | Sodium borohydride | HCID 4311764 | — |
| Solvent | Methanol | HCID 887 | — |
| Product | 1-(5-Methyl-2-thienyl)ethanol | HCID 15091795 | 98.1% |
Reaction Steps
Add sodium borohydride (270 mg, 7.13 mmol) to a solution of 2-acetyl-5-methylthiophene (1.0 g, 7.13 mmol) in methanol (40 mL). Stir the mixture for 1 h at room temperature. Remove the solvent in vacuo and partition the residue between water and DCM. Separate the organic phase, dry over Na2SO4, filter and concentrate to obtain the desired intermediate as an oil (0.995 g, 98%) that was used without further purification. GC-MS m/z 142 (M+).
