Reaction Steps

4-[2-(4-Trifluoromethyl-phenoxy)-phenylcarbamoyl]-piperidine-1-carboxylic acid tert-butyl ester (HVB01043, 0.2 g, 0.43 mmol) was dissolved in anhydrous DCM (5 ml), cooled to 0° C. and to this was added TFA (2.3 ml), and the reaction mixture was stirred under nitrogen for 1 h. The reaction mixture was poured onto solid potassium carbonate (6 g), and water (25 ml) added. Extracted with DCM and the organic layers dried over anhydrous magnesium sulphate, and evaporated in-vacuo, to afford an off white oil, 0.14 g, 89%. Rf: 0.47 (DCM), 1HNMR: (CDCl3, 270 MHz) δ 1.65 (2H, m, CHCH2), 1.79 (2H, m, CHCH2), 2.30 (1H, m, CH), 2.64 (2H, td, J=12.4, 2.7 Hz, NCH2), 3.10 (2H, m, NCH2), 6.97 (1H, dd, J=6.4, 30.5 Hz, Ar HD), 7.05 (2H, m, Ar HF), 7.06 (1H, m, Ar HB), 7.17 (1 h, t, J=7.2 Hz, Ar HC), 7.58, d, J=8.6 Hz, Ar HE), 8.39 (1H, d, J=7.9 Hz, Ar HA).
