実験手順

A mixture of 4-[(2-Bromo-decyl)-[1,2,4]triazol-4-yl-amino]-benzonitrile (CAB03008, 607 mg, 1.5 mmol), 4-hydroxy-thiophenol (378 mg, 3.0 mmol) and potassium carbonate (414 mg, 3.0 mmol) in DMF (10 mL) was stirred for 12 hours at room temperature. The mixture was transferred into a separation funnel and ethyl acetate (50 mL) and water (50 mL) were added. The organic layer was separated, washed with brine (30 mL), dried over sodium sulphate and concentrated under reduced pressure. The residue was purified by column chromatography (eluent: ethyl acetate, Rf: 0.71). The resulting yellow solid was dissolved in acetone and precipitated by addition of hexane to give a light yellow powder. Yield: 401 mg (59%). 1H-NMR (400 MHz, d6-DMSO) δ=1.16-1.52 (m, 16H), 2.76 (t, J=7.2 Hz, 2H), 3.80 (t, J=7.2 Hz, 2H), 6.62 (d, J=9.0 Hz, 2H), 6.72 (d, J=8.6 Hz, 2H), 7.19 (d, J=8.6 Hz, 2H), 7.72 (d, J=9.0 Hz, 2H), 8.97 (s, 2H), 9.53 (s, 1H, —OH). LRMS (FAB+): 450.2 (100, [M+H]+). HRMS (FAB+) 450.23208 C25H32N5OS requires 450.232758.
