Hydrochloric Acid → 3-Cyano-4-isobutylbenzoic acid

Participants

Reaction Steps

Methyl 3-cyano-4-(2-methylpropyl)benzoate (D24) (233 mg, 1.072 mmol) was dissolved in ethanol (4 ml) and 2M aqueous sodium hydroxide (1 ml, 2 mmol) was added. The reaction was stirred for 1 h. 2M aqueous HCl (10 mL) was added and the mixture extracted with dichloromethane (20 mL+10 mL). The organic phases were isolated and dried by phase separator and combined before the solvent was removed in vacuo to give the title compound as a white solid (203 mg, 0.999 mmol). MS (ES): C12H13NO2 requires 203; found 202 (M−H+).
