Reaction Steps

To a solution of 3-((5-methyl-3-(3-(4-(trifluoromethoxy)phenyl)-1,2,4-oxadiazol-5-yl)-1H-1,2,4-triazol-1-yl)methyl)benzene-1-sulfonyl chloride (50 mg, 0.1 mmol) in DCM (5 mL) were added pyridine (0.05 ml) and 1-methylpiperazine (20 mg, 0.2 mmol). The mixture was stirred at RT for 1 h, then diluted with DCM and washed with H2O (100 mL). The aqueous layer was separated and extracted with DCM (2×100 mL), the combined organic layers were washed with brine (100 mL), dried (Na2SO4) and concentrated under reduced pressure. The residue was purified by prep-HPLC (Mobile phase: A=0.1% formic acid/H2O, B=MeCN; Gradient: B=36%-95% in 18 min; Column: XBridge C18, 5 um, 30 mm×150 mm) to give the title compound as a white solid; MS (ES+) C21H19F3N6O4S requires: 508. found: 509 (M+H)+; 1H NMR (500 MHz, DMSO-d6) δ ppm 8.28 (d, J=8 Hz, 2H), 7.86 (bs, 1H), 7.84 (m, 1H), 7.64 (m, 2H), 7.50 (d, J=7.5 Hz, 2H), 5.67 (s, 2H), 3.98 (m, 2H), 3.61 (m, 2H), 3.26 (m, 2H), 2.90 (s, 3H), 2.74 (m, 2H), 2.69 (s, 3H).
