Procedure
The potassium hydroxide (54.6 mg, 0.97 mmol) was added to a station (S)-isopropyl 2-(tert-butoxy)-2-(5-(4-(4-fluorophenethoxy)phenyl)-2,6-dimethyl-4-(4-(propan-2-ylidene)piperidin-1-yl)pyridin-3-yl)acetate (60 mg, 0.097 mmol) in ethanol (2 mL) and stirred for 6 h at 90° C. The reaction mixture was neutralized with 1N HCl solution, extracted with EtOAc, and the organic layer was washed with brine, and dried (MgSO4). The crude material was purified by prep HPLC to afford (S)-2-(tert-butoxy)-2-(5-(4-(4-fluorophenethoxy)phenyl)-2,6-dimethyl-4-(4-(propan-2-ylidene)piperidin-1-yl)pyridin-3-yl)acetic acid 39.3 mg (70%). 1H NMR (500 MHz, DMSO-d6) δ 7.38-7.35 (m, 2H), 7.19 (d, J=8.4 Hz, 1H), 7.13 (t, J=8.4 Hz, 2H), 6.97 (t, J=8.1 Hz, 2H), 6.90 (d, J=8.1 Hz, 1H), 5.84 (s, 1H), 4.21 (t, J=6.2 Hz, 2H), 3.53 (br. s, 4H), 3.04 (t, J=6.2 Hz, 2H), 2.44 (s, 3H), 2.31-2.28 (m, 1H), 2.05 (br. s, 1H), 2.00 (s, 3H), 1.83 (br. s, 1H), 1.65 (br. s, 1H), 1.56 (s, 3H), 1.49 (s, 3H), 1.12 (s, 9H). UPLC (M+H)=575.3.
