Triethylamine → HCID 86711933, Verbindung

To a solution of 5-(5-methyl-1-(3-(piperazin-1-yl)benzyl)-1H-1,2,4-triazol-3-yl)-3-(4-(trifluoromethoxy)phenyl)-1,2,4-oxadiazole (Example 81; 110 mg, 0.23 mmol) and Et3N (70 mg, 0.69 mmol) in DCM (5 mL) at 0° C. was added methanesulfonyl chloride (34 mg, 0.30 mmol). The reaction mixture was allowed to warm to RT over 2 h, then diluted with H2O (10 mL) and extracted with EtOAc (2×10 mL). The combined organic layers were washed with H2O (10 mL) and brine (10 mL), dried over Na2SO4, filtered and concentrated under reduced pressure; the residue was purified by prep-HPLC (10% to 30% MeCN/H2O containing 0.1% trifluoroacetic acid) to give the title compound as an off-white solid; MS (ES+) C24H24F3N7O4S requires: 563. found: 564 [M+H]+; 1H-NMR (500 MHz, DMSO-d6) δ 8.22 (d, J=8.5 Hz, 2H), 7.61 (d, J=8.5 Hz, 2H), 7.24 (m, 1H), 6.96 (m, 2H), 6.70 (d, J=7.5 Hz, 1H), 5.49 (s, 2H), 3.98 (m, 4H), 3.25 (m, 4H), 2.92 (s, 3H), 2.58 (s, 3H).
