Ethanethiol → HCID 21480631, compound

Participants

Reaction Steps

To a solution of the 1-(9,10-dihydro-9,10-methanoanthracen-9-ylmethyl)-4-(2-fluoro-3-pyridyl)piperidin-4-ol (described in e. above) (2.00 g, 5.00 mmol, 1 eq) in THF (50 mL) under nitrogen was added the sodium salt of ethanethiol (0.90 g, 10.7 mmol, 2.2 eq). The thiolate salt was prepared from ethanethiol and sodium hydride under standard conditions. The reaction was heated to reflux for 18 h and quenched by pouring into water (100 mL). The aqueous phase was extracted with diethyl ether (2×100 mL), dried over anhydrous sodium sulfate, filtered, and reduced to an oil. The reaction product was purified by flash chromatography over silica gel (200 mL, eluent: 50% ether in hexane) to yield 2.00 g (90%) of the title compound. TLC analysis (Rf 0.29, 50% ether in hexane).
