Reaction Steps

To a stirred solution of 6′-cyano-3,4,5,6-tetrahydro-2H-[1,3]bipyridinyl-4-carboxylic acid ethyl ester (1.61 g, 6.20 mmol) in THF (30 mL), H2O (30 mL) and MeOH (3 mL) was added LiOH.H2O (326 mg, 7.76 mmol). 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 product extracted with EtOAc, dried over Na2SO4. The resulting solid was suspended in heptane, filtered off, washed with cold Et2O to give 1.40 g (99%) of 6′-cyano-3,4,5,6-tetrahydro-2H-[1,3]bipyridinyl-4-carboxylic acid. ES-MS m/e: 230.1 (M−H+)
