実験手順

To a solution of N-(5-chloropyridin-2-yl)-2-aminobenzamide(0.247 g, 1 mmol) in dichloromethane (10 mL) and pyridine (0.5 mL) was added a solution of 4-biphenylcarbonyl chloride (0.217 g, 1 mmol) in dichloromethane (5 mL). After stirring overnight the solvent was removed in vacuo. The residue was partitioned between ethyl acetate (50 mL) and water (25 mL). Separate the layers and wash the organic layer with water (2×10 mL), saturated sodium bicarbonate (2×20 mL), hydrochloric acid (0.2 N, 1×20 mL). Dried over MgSO4, filtered and concentrated in vacuo. The residue was then purified by RPHPLC (30% ethyl acetate/hexane) to give 0.4 g (94%) of pure product.
