Participants

Reaction Steps

23 cm3 (0.083 mol) of triethyl-amine are added to the solution of 23 cm3 of dichloro methane and 11.5 g (0.083 mol) 4,5,6,7-tetrahydro-thieno[3,2-c]pyridine dropwise at room temperature and 23 g (0.083 mol) of trityl-chloride are further added to the mixture. The reaction mixture is kept at room temperature for one night and poured onto 2000 ml of water. The organic phase is separated, dried with sodium sulfate and evaporated. The colorless, paste-like crystals are dried in vacuo for 5 hours at 80° C. under 140 mbar pressure.
