Reaction Steps

Potassium hydroxide powder (0.373 g, 12.005 mmol) and EtOH (0.3 mL, 6.002 mmol) were added to a solution of 6-chloropyridine-3-carboxylic acid (0.473 g, 3.001 mmol) in DMSO (12 mL) at room temperature. The reaction mixture was heated at 100 C for 21 h, and cooled to room temperature. A 1M aqueous solution of HCl was added. The resulting precipitate was collected by filtration, washed with water and dried under vacuum to afford the title compound (356 mg, 71%). Method B HPLC-MS: MH+ requires m/z=168. Found: m/z=168, Rt=1.50 min (95%).
