Reaction Steps

A mixture of Methyl 5-cyano-1-cyclopentyl-6-oxo-1,6-dihydropyridine-3-carboxylate (290 mg, 1.2 mmol) and 1N sodium hydroxide (6 mL, 6.0 mmol) in methanol (12 mL) was heated to reflux for 1 h and brought to RT. The mixture was concentrated and the residue obtained was dissolved in ethylacetate (20 mL), acidified with 1N hydrochloric acid (pH ˜5). The organic phase was separated, dried over magnesium sulfate and concentrated to afford the title compound as a light yellow solid. MS m/z: 233 (M+1).
