Abstract
An object of the present invention is to provide a process for producing 2-(4-pyridyl)ethanethiol easily. According to the invention, 4-vinylpyridine is reacted with thiourea in an aqueous medium containing an acid to form a solution containing an isothiuronium salt and then the solution is made alkaline to convert the isothiuronium salt into 2-(4-pyridyl)ethanethiol.
