Reaction Conditions

Reaction Steps

A mixture of pyridine-3-aldehyde (21.4 g), 2,4-dichlorophenylacetic acid (40.1 g), triethylamine (20 ml) and acetic anhydride (160 ml) was stirred and heated under reflux for 5 hours while maintaining a temperature of 150° C. After cooling, the reaction mixture was diluted with water (150 ml) and left to stand overnight. The crystalline solid that had separated was filtered off, washed thoroughly with water and dried. After recrystallization from ethanol (600 ml) 1 was obtained as pale yellow crystals; melting point 208-211° C.; yield 71%. The following elemental analysis results were obtained:
