실험 절차

A mixture of 6-chloro-1-methyl-1H-imidazo[4,5-c]pyridine-4-carbonitrile (6 g), 4-(3-hydroxypropoxy)-3-(trifluoromethyl)phenylboronic acid (12.3 g), tris(dibenzylideneacetone)dipalladium (1.42 g), tricyclohexylphosphoine (1.05) and tribasic potassium phosphate (13.2 g) in dioxane (60 ml) and water (24 ml) was heated at 100° C. under N2 for 4 hours. The mixture was then diluted with ethyl acetate (400 ml) organic layer separated and solvent removed under reduced pressure, to the residue was then added methanol (50 ml), product crystalised out and collected by filtration (7.7 g).
