Participants

Reaction Conditions

Reaction Steps

In 50 ml of ethanol were dispersed 3.03 g of 2-hydrazino-5-nitropyridine and 3.08 g of 4-isopropylbenzaldehyde. The dispersion was refluxed at 90° C. for one hour. 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 a small amount of ethanol and dried in vacuum at 60° C. for 1.5 hours, obtaining 3.51 g (yield 62%) of dark yellow acicular crystals.
