실험 절차
A mixture of 13.0 g of N-(2-hydroxyphenyl)-2-chloro-3-pyridinecarboxamide and 2.82 g of sodium methoxide in 100 ml of N,N-dimethylformamide is refluxed under argon for 3 hours. Sodium methoxide (0.50 g) is added and the mixture refluxed 2 hours and then stirred at room temperature for 2 days. The solvent is removed under high vacuum and the red-brown residue triturated with cold methanol. The mixture is filtered and the solid washed with chilled methanol to give 5.0 g of white solid, m.p. 250°-253° C.
