A mixture of 3-benzyloxy-2,2-dimethylpropanenitrile (2.5 g, 13.2 mmol), 10% aqueous sodium hydroxide (10 mL) and methanol (150 mL) was heated 8 hours at reflux and then concentrated. The residue was dissolved in water (30 mL) and the solution was washed with dichloromethane (2×10 mL), treated with 10% hydrochloric acid and extracted with ethyl acetate (4×20 mL). The combined extracts were washed with water and brine, dried (MgSO4) and concentrated to give 3-benzyloxy-2,2-dimethylpropionic acid (1.6 g, 7.5 mmol).
