Procedure

Methyl 1-(3-(6-(1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropane-carboxamido)-3-methylpyridin-2-yl)phenyl)cyclopropanecarboxylate (˜0.26 mmol) was dissolved in acetone (3 mL) and water (3 mL) in a reaction tube. LiOH.H2O (25 mg, 60 mmol) was added, and the reaction mixture was stirred at room temperature for 16 hours. The mixture was acidified with 1N HCl until pH 1-2. The volatiles were removed under reduced pressure. The residue was taken up in methylene chloride and the organic layer was dried over Na2SO4 and concentrated under reduced pressure. The solid was triturated with Et2O, then hexanes to 1-(3-(6-(1-(2,2-difluorobenzo[d][1,3]dioxol-5-yl)cyclopropane-carboxamido)-3-methylpyridin-2-yl)phenyl)cyclopropanecarboxylic acid. ESI-MS m/z 493.2 (M+1)+. Retention time 1.80 minutes.
