Reaction Steps

To a solution of methyl 3-cyclopropylpyridine-2-carboxylate (80 mg, 0.45 mmol) in THF (2 ml) and water (2 ml) was added lithium hydroxide (55 mg, 1.36 mmol) and the reaction mixture was refluxed for 2 hours. The reaction was then acidified to pH 2 using 1M HCl (aq) and extracted with DCM (3×50 ml). The combined organics were washed with water (30 ml), brine (30 ml), dried over sodium sulfate and concentrated in vacuo to afford the title compound.
