반응 단계

6.12 g (12.28 mmol) of 2-bromo-1-(5,5,8,8-tetramethyl-5,6,7,8-tetrahydronaphthalen-2-yl)ethanone and 3 g (12.28 mmol) of 4-thiocarbamoylpiperidine-1-carboxylic acid tert-butyl ester were suspended in 50 ml of ethanol and refluxed overnight. The reaction mixture was cooled and evaporated. The residue was slurried using a little EA and PE, digested and filtered off with suction. The solid was suspended in 180 ml of EA, washed with 60 ml of a saturated sodium hydrogencarbonate solution. The organic phase was dried over sodium sulfate, filtered and evaporated.
