Procedure

25 g of K2CO3 are added to a solution of 20 g of phenylhydrazine hydrochloride in 150 ml of methyl formate and 60 ml of water, and the mixture is refluxed for 1 hour and left at AT for 12 hours with stirring. The precipitate formed is filter-dried, and washed with a propan-2-ol/petroleum ether mixture. 18.8 g of the expected compound are obtained.
