Reaction Conditions

Reaction Steps

To a solution of [4-(4-fluoro-benzoyl)-piperidin-1-yl]-acetic acid (561 mg, 2.11 mmol) in water (10 mL) and was added 2-butyn-1-ol (3.71 g, 52.9 mmol) followed by a solution of 4N NaOH (3.44 mL, 13.8 mmol). The reaction was heated up to 80° C. for 72 hours. The reaction was acidified using 2N HCl to pH 5, then the solvent was then removed under vacuum to afford the crude title compound (2.0 g). LRMS m/z: ES+=315.9 (M+H), retention time 1.52.
