実験手順

A mixture of 2-chloro-pyridine-4-carboxylic acid (300 mg, 1.9 mmol), benzylmethylamine (230 mg, 1.9 mmol) and triethylamine (192 mg, 1.9 mmol) is heated at 120° C. for 12 h. The residue is dissolved in CH2Cl2 (30 mL) and extracted with 1M aqueous NaOH (3×5 mL). The aqueous layer is adjusted to pH 1-2 with 12N aqueous HCl and extracted with EtOAc (6×5 mL). The organic extracts are combined, dried (MgSO4), and evaporated to provide the title compound.
