実験手順

To a solution of quinoline-6-carboxamide (177 g, 1.03 mol) in chloroform (1.5 lit.) and triethylamine (520.15 g, 5.15 mol), trifluoroacetic anhydride (540.34 g, 2.57 mol) was added dropwise below 10° C. After 1.5 h, the pH was adjusted to 7 with sodium bicarbonate solution and extracted with dichloromethane. The organic layer was dried with sodium sulphate and concentrated to afford the title compound as a brown solid (96 g, 59%).
