Reaction Steps
A mixture of methyl 2-(1-tert-butoxycarbonylpiperidin-4-yloxy)-4-fluorobenzoate (3.05 g, 8.64 mmol), 1 M aq LiOH (15 mL, 15 mmol), MeOH (15 mL), and THF (45 mL) was stirred overnight. The reaction mixture was diluted with EtOAc, washed with satd citric acid, dried over MgSO4, concentrated, and triturated with ether to give the acid as a white solid (2.23 g, 76%).
