Reaction Steps
To 10 ml of N,N-dimethylformamide were dissolved 0.29 g (1.1 mmol) of 8,8-difluoro-7-methyl-7-octenyl methanesulfonate and 0.26 g (1.5 mmol) of benzo[b]thiophene-2-carboxylic acid, followed by the addition of 0.28 g (3.3 mmol) of sodium hydrogencarbonate and stirring at 100° C. for 3 hours. The reaction liquid was then poured in water and extracted with diethyl ether. The organic layer was washed with water and a saturated saline solution in this order, followed by drying over anhydrous magnesium sulfate and concentration under reduced pressure. The residue was purified with silica gel column chromatography (diisopropyl ether:hexane=1:8) to obtain 0.27 g (yield: 71%) of 8,8-difluoro-7-methyl-7-octenyl benzo[b]thiophene-2-carboxylate.
