Procedure

A mixture of trifluoromethanesulfonic acid 8-chloro-3-(4-chlorobenzyl)-2,4-dimethyl-quinolin-5-yl ester (0.29 g), zinc cyanide (0.036 g), tetrakis(triphenylphosphine)palladium(0), (0.071 g) in N,N-dimethylformamide (8.0 mL) was heated by microwave irradiation at 125° C. for 10 minutes. The mixture was diluted with water and the resulting precipitate collected by filtration and then purified by column chromatography on silica gel, eluting with a mixture of cyclohexane, dichloromethane and ethyl acetate (1:1:0 to 0:1:0 to 0:20:1 by volume) to afford title compound as a white solid, 0.17 g.
