Versuchsvorschrift

In 333 ml of methanol was dissolved 8.6 g of 2-methyl-4-amino-5-formylpyrimidine. To the solution was added gradually 10.6 g of phenyl hydrazine hydrochloride. As the reaction proceeded, crystals precipitated out. Five hours later, the crystals were collected by filtration and dried under reduced pressure to obtain 16.5 g (93%) of 1-(2-methyl-4-aminopyrimidyl)methylidene-2-phenylhydrazine hydrochloride. Physical properties of 1-(2-methyl-4-aminopyrimidyl)methylidene-2-phenylhydrazine hydrochloride are as follows:
