Reaction Conditions

Reaction Steps

In 20 ml of ethanol was dissolved 5.46 g of 2-hydrazinopyridine. With 7.41 g of 4-isopropylbenzaldehyde added, the solution was agitated. Fine crystals started precipitating within about 30 seconds and the entire solution solidified within about 1 minute. 10 ml of ethanol was added to the mass, which was refluxed at 100° C. for 40 minutes. The reaction solution was allowed to cool at room temperature and further cooled down to 5° to 10° C. to cause crystals to fully precipitate, which were collected by suction filtration. The crystals were washed with ethanol and dried in vacuum for 40 minutes, obtaining 9.09 g (yield 76%) of pale yellow acicular crystals.
