Participants

Reaction Steps

11.7 g (25.6 mmol) of 3-butoxy-4,7-difluoro-8-(4-pentylcyclohexyl)-benzo[c]chromen-6-one and 11.4 g (28.2 mmol) of Lawesson's reagent were refluxed for 16 hours in 130 ml of chlorobenzene. The solution was subsequently filtered through silica gel and evaporated, and the crude product was purified by crystallisation from MTB ether, giving 7.9 g (65%) of 3-butoxy-4,7-difluoro-8-(4-pentylcyclohexyl)benzo[c]chromene-6-thione as yellow crystals.
