Vorschrift

A solution of 1-chloro-3-(2-trifluoromethyl-phenyl)-isoquinoline (0.326 mmol) and 1H-[1,2,4]triazol-3-ylamine (0.651 mmol) in ethanol (3 mL) was heated at 160° C. and the solvent evaporated with a stream of nitrogen. The remaining oil was then heated at 160° C. for 18 hours under nitrogen. The resulting melt was dissolved in 5% methanol/dichloromethane (50 mL), washed with saturated aqueous sodium bicarbonate (1×25 mL) then dried over magnesium sulfate. Purification by silica gel chromatography afforded IX-175 as a colorless oil (4% yield). 1H NMR (500 MHz, CDCl3) δ 9.18 (d, 1H), 8.82 (s, 1H), 7.90 (d, 1H), 7.85-7.75 (m, 3H), 7.71-7.62 (m, 3H), 7.60-7.55 (m, 2H), 4.42-4.35 (m, 1H). LC-MS (ES+) 356.16 (M+H); HPLC-Method D, Rt 3.55 min.
