Procedure
To a solution of 4-(2-fluoro-4-methylthio-5-methoxycarbonylphenyl)-N-Cbz-piperidine (1.38 g) dissolved in 100 mL 1:1 THF:H2O was added 0.45 g LiOH. Mixture was stirred for 18 h, THF was evaporated, residue was mixed with 25 mL 1N HCl, and extracted with DCM (3×50 mL). Extracts were combined, dried over Na2SO4, and evaporated to give 1.33 g product; MS m/z 404 (M+H); 1H NMR (CDCl3) δ 8.01 (d), 7.45-7.25 (m), 6.94 (d), 5.17 (s), 4.50-4.21 (m), 2.99 (tt), 3.01-2.78 (m), 2.44 (s), 1.84 (dm), 1.69 (qd).
