Acetonitrile → HCID 66656004, compound

Participants

Reaction Steps

To a stirred solution of piperidine-4-carboxylic acid ethyl ester (12.6 g, 0.080 mol) in CH3CN (250 mol), iPr2Net (33.7 mL, 0.193 mol) and 1-(6-chloro-pyridin-3-yl)-ethanone (10 g, 0.064 mol) were added. The reaction mixture was heated at reflux over night, and then volatiles evaporated under high vacuum. Column chromatography (SiO2, EtOAc/heptane, 1:9 to 1:1) yielded 15.9 g (89%) of 5′-acetyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carboxylic acid ethyl ester as a yellow oil. ES-MS m/e: 277.2 (M+H+).
