Participants

Reaction Steps

To a stirred solution of 5′-acetyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carboxylic acid ethyl ester (15.8 g, 0.057 mol) in THF (75 mL), H2O (75 mL) and MeOH (8 mL) was added LiOH.H2O (2.64 g, 0.0629 mol). Stirring was continued overnight at RT before the organic solvent were removed under vacuo. The pH of the was adjusted to 5 with acetic acid, and the white precipitate was filtered off and dried to yield 13 g (92%) of 5′-Acetyl-3,4,5,6-tetrahydro-2H-[1,2′]bipyridinyl-4-carboxylic acid. ES-MS m/e: 249.2 (M−H+)
