Dichloromethane → 5-(Triphenylmethyl)-4,5,6,7-tetrahydrothieno[3,2-c]pyridine

Participants

Reaction Steps

20 cm3 (0.079 mole) of triethyl amine are added dropwise to the solution of 10 g (0.072 mole) of 4,5,6,7-tetrahydro-thieno[3,2-c]pyridine and 20 cm3 of dichloro methane at room temperature and 20.02 g (0.072 mole) of triphenyl-methyl-chloride are added. The reaction mixture is kept at room temperature for a night and is poured onto 200 cm3 of water. The phases are separated; the organic phase is dried on sodium sulfate and evaporated to dryness. The residual product is purified by silica gel chromatography using dichloro methane as eluent.
