実験手順

A mixture of 0.31 g (0.62 mmol) of 8-(2-chloroethoxy)-4-(2,4-dichloro-5-methoxyphenylamino)-7-methoxybenzo[g]quinoline-3-carbonitrile, 0.36 mL (6.1 mmol) of 1H-1,2,3-triazole and 0.11 g (2.8 mmol) of sodium hydroxide powder in 5 mL of N,N-dimethyl formamide is heated at 80° C. for 4.5 hours, then cooled and poured on to ice. The solid is collected by filtration, washed with water and dried. The two isomers are separated by silica gel flash chromatography, using first 7:3 ethyl acetate/hexane, then a 100:0 to 9:1 gradient of ethyl acetate/methanol. The less polar material, 0.071 g of 4-(2,4-dichloro-5-methoxyphenylamino)-7-methoxy-8-(2-[1,2,3]triazol-2-yl-ethoxy)benzo[g]quinoline-3-carbonitrile, is obtained as yellow solid, mp 285-287° C.
