4-(Octyloxy)benzoic acid → 4-Octyloxybenzoyl chloride

Participants

Reaction Steps

20 ml of SOCl2 was added to 4.0 g (1.6×10-2 mol) of 4-octyloxybenzoic acid, and the mixture was refluxed under heating for 4 hours. Excessive SOCl2 was distilled off to obtain 4-octyloxybenzoic acid chloride. 3.136 g (1.6×10-2 mol) of 4-(2'-methylbutyloxy)benzenethiol and 1.246 g of pyridine were dissolved in 12 ml of toluene, cooled with ice, and the 4-octyloxybenzoic acid chloride dissolved in 10 ml of toluene was added thereto. The mixture was left standing at 5° C. for 45 min, followed by stirring for 3.5 hours at room temperature.
