Procedure
N-[4-[2-(4-Amino-piperidin-1-yl)-ethoxy]-3-(4-chloro-2-methyl-2H-pyrazol-3-yl)-phenyl]-3-trifluoromethyl-benzamide (0.038 g, 0.073 mmol) was dissolved in DMA (2.0 mL) in a vial with stir bar. Methanesulfonyl chloride (0.0085 g, 0.11 mmol) was added and the reaction was stirred at rt overnight. The reaction was concentrated, added to NaHCO3 (5 mL), and the solution was extracted with EtOAc (2×20 mL). The organic extracts were dried (Na2SO4), filtered, concd and purified by prep HPLC to afford the title compound (0.016 g, 0.026 mmol, 35%, TFA salt) as a white solid. LCMS m/z (%)=600 (M+H35Cl, 100), 602 (M+H37Cl, 36). 1H NMR (400 MHz, DMSO-d6) δ: 10.54 (s, 1H), 9.30 (s, 1H), 8.30 (s, 1H), 8.26 (d, J=8.0 Hz, 1H), 7.97 (m, 2H), 7.80 (m, 1H), 7.72 (d, J=2.6 Hz, 1H), 7.68 (s, 1H), 7.31 (m, 1H), 4.40 (m, 1H), 4.32 (m, 1H), 3.69 (s, 3H), 3.50-2.90 (m, 7H), 2.95 (s, 3H), 2.00-1.50 (m, 4H).
