Reaction Steps

A mixture of 1-[2,4-dichloro-3-[2-methyl-4-(pyrazol-1-yl)quinolin-8-yloxymethyl]phenyl]-2-formylpyrrole (80 mg), hydroxylamine hydrochloride (18 mg), sodium acetate (21 mg) and ethanol (60° solution in water, 1.5 ml) was stirred at 60° C. for 1 hour. After cooling to ambient temperature, the reaction mixture was concentrated in vacuo. The residue was dissolved in ethyl acetate, washed with water and brine, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin-layer chromatography (n-hexane:ethyl acetate=1:1, V/V) to give 1-[2,4-dichloro-3-[2-methyl-4-(pyrazol-1-yl)quinolin-8-yloxymethyl]phenyl]-2-((E)-hydroxyiminomethyl)pyrrole (45 mg) as an amorphous powder and 1-[2,4-dichloro-3-[2-methyl-4-(pyrazol-1-yl)quinolin-8-yloxymethyl]phenyl]-2-((Z) -hydroxyiminomethyl)pyrrole (14 mg) as an amorphous powder.
