Potassium Hydroxide → 2-(Hydroxymethyl)-5-methylbenzoic acid

참여 물질

반응 단계

A colorless, homogeneous solution of 6-methylisobenzofuran-1(3H)-one (0.95 g, 6.41 mmol), KOH (0.576 g, 10.26 mmol) in methanol (20.52 mL) and water (5.13 mL) was refluxed. After two hr, the reaction was cooled to room temperature, concentrated in vacuo, and acidified with 1 M aqueous KHSO4 to pH ˜3. The mixture was extracted with EtOAc (4×50 mL). The combined extract was dried over MgSO4 and concentrated in vacuo to give the desired product (0.632 g, 3.81 mmol, 59.4% yield) as a white solid.
