Triethylamine → HCID 39240504, compound

Participants

Reaction Steps

In a dry round bottom flask was placed 4-cyanopiperidinium chloride (13, 5 g, 45.4 mmol) dichloromethane (150 ml) and triethylamine (18.98 ml, 136 mmol). To the reaction was added dropwise ethanesulfonyl chloride (4.56 ml, 45.4 mmol) and the solution stirred 1 hour and quenched with water (100 ml). The mixture was extracted with dichloromethane (3×50 ml) and the combined organic fractions dried (MgSO4), filtered, and the solvent evaporated under reduced pressure. The residue was purified by column chromatography on silica gel, eluting with EtOAc/Hexanes to give 1-(ethylsulfonyl)piperidine-4-carbonitrile (14) as a white solid. MS 203 (M+1)
