実験手順

To a solution of 8-trifluoromethyl-quinolin-4-ol (107 mg, 0.50 mmol) in THF (5 mL) was added 4-isocyanatobenzene-sulfonyl chloride (109 mg, 0.50 mmol) at RT. The resulting mixture was stirred at ambient temperature for 1 h. Then, a solution of 2-aminothiazole (50 mg, 0.50 mmol) in pyridine (5 mL) was added and stirring was continued for 65 h. The solvents were evaporated under a stream of nitrogen, the residue was dissolved in DMSO (2 mL) and purified by preparative LC/MS (gradient of 5-95% CH3CN/water). 1H-NMR (DMSO-d6) δ 9.63 (s, 1H), 9.10 (s, 1H) 8.28-8.22 (m, 2H), 7.97-7.95 (m, 2H), 7.81-7.77 (m, 3H), 7.52-7.51 (m, 1H), 7.41-7.40 (m, 2H), 7.15-7.14 (m, 1H). LC/MS (5-95%) M/Z: M+1 obs=495.4; tR=10.45.
