실험 절차
A mixture of 2-chloro-5-nitro-N-(3-hydroxytol-4-yl)-3-pyridinecarboxamide (6.3 g, 0.02 mol) and pyridine (100 ml) was heated under argon at 90° C. for 2.5 hours. The cooled solution was diluted with water and the yellow-orange precipitate collected and washed with water. The solid was then stirred in hot water (100 ml) for 45 min., filtered and washed with ethanol and ether to give 4.3 g of a tan-brown solid. Recrystallization from dimethylformamide/water afforded 3.76 g (69% of theory) of product.
