Use	organic intermediates.
production method	obtained by chloromethylation of thiophene: add 40% formaldehyde and concentrated hydrochloric acid into the reactor, after cooling with stirring to -5 °c, thiophene is added and dry hydrogen chloride is passed under cooling with vigorous stirring until there is significant evolution of hydrogen chloride from the tail gas. The obtained organic layer was separated, dried over anhydrous sodium sulfate, filtered off the desiccant, and distilled under reduced pressure to collect a 78-82 ° C. (2.4kPa) fraction. 2-chloromethylthiophene was obtained. The yield was 45%-49%.
