Triethylamine → HCID 67174054, compound

Participants

Reaction Steps

In a dry round bottom flask was placed 4-cyano-4-(tetrahydro-2H-pyran-4-ylmethyl)piperidinium chloride (9, 1 g, 3.1 mmol), dichloromethane (50 ml) and triethylamine (2.162 ml, 15.51 mmol). To this was added dropwise ethanesulfonyl chloride (0.317 ml, 3.1 mmol). The reaction was stirred 1 hour and quenched with water (100 ml). The mixture was extracted with dichloromethane (3×50 ml) and the combined organic fractions were 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)-4-(tetrahydro-2H-pyran-4-ylmethyl)piperidine-4-carbonitrile (10) as a white solid.
