Reaction Steps

2-Chloro-3-cyanopyridine is reacted with 4-methoxyphenol in the presence of sodium hydride in dimethylformamide to give 2-(4-methoxyphenoxy)-3-cyanopyridine, which is subjected to Grignard reaction with 2-bromothiophene in a mixed solvent of ether and benzene, followed by treatment with hydrochloric acid to give 2-(4-methoxyphenoxy)-3-(2-thenoyl)pyridine. The thus obtained compound is subjected to demethylation reaction with the use of aluminium chloride and 1-butanethiol in dichloromethane to give 2-(4-hydroxyphenoxy)-3-(2-thenoyl)pyridine.
