Participants

Reaction Steps

[2-(4-Chloro-2-methylquinolin-8-yloxy)-ethyl]-carbamate tert-butyl ester (1.30 g, 3.86 mmole), 3,4-dichlorobenzylamine (1.36 g, 7.72 mmole) and a catalytic effective amount of copper(II)sulphate pentahydrate in dimethylsulfoxide (0.2 mL) were stirred at 155° C. for 30 min in a microwave oven. The organic phases were washed with water and saturated NaCl solution, dried and the solvent was removed. The residue thus obtained was purified using silica gel chromatography, eluting with dichloromethane:water 90:10. Precipitation in ethyl acetate gave a brownish solid (230 mg, 13%).
