실험 절차

A mixture of {4-difluoromethoxy-2-ethyl-8-fluoro-3-[4-(4,4,5,5-tetramethyl[1,3,2]dioxaborolan-2-yl)benzyl]quinolin-5-yloxy}acetic acid methyl ester (0.14 g), 4-chloro-1H-pyrazole (0.053 g), cuprous acetate (0.093 g) and pyridine (3 mL) was heated at 50° C. for 116 hours. The mixture was cooled to room temperature, diluted with water (10 mL) and extracted with ethyl acetate. The combined extracts were washed with saturated aqueous sodium chloride solution, dried over magnesium sulphate and then concentrated under reduced pressure. Purification of the residue by column chromatography silica gel, eluting with a mixture of cyclohexane and ethyl acetate (1:0 to 7:3 by volume) gave title compound as a colourless oil (0.13 g).
