実験手順

To a solution obtained by suspending 2.25 g (93 mmol) of magnesium in 50 mL of THF, a solution of 20.0 g (71 mmol) of 4-(trans-4-propylcyclohexyl)phenyl bromide in 100 mL of THF was added dropwise with stirring at the room temperature for 45 minutes and stirred with reflux for 30 minutes, to prepare a Grignard reagent. To the solution, 16.3 g (214 mmol) of carbon disulfide was added dropwise for 15 minutes at the room temperature and stirred for one night. To the reaction solution, 60 mL of 3M hydrochloric acid was added to stop the reaction, extracted with ether, and dried with anhydrous magnesium sulfate. After filtering off magnesium sulfate, the filtrate was concentrated under reduced pressure, to obtain 3.5 g (yield 17.7%) of 4-(trans-4-propylcyclohexy)phenyl dithiocarboxylic acid.
