Procedure

The mixture of N-methoxy-2-(2-(4-methoxyphenyl)cyclopropyl)-N-methylacetamide (559) (1.8 g, 7.4 mmol), 2.5N NaOH (15 mL) and EtOH (15 mL) was stirred at 60° C. for 24 hours. The reaction mixture was acidified with HCl and extracted with EtOAc. The organic phase was washed with water, brine, dried over sodium sulfate and concentrated in vacuo to provide 2-(2-(4-methoxyphenyl)cyclopropyl)acetic acid (560) (1.5 g, 96.1%) as a yellow solid.
