Procedure
12.4 g of the 5-[(2'-cyanobiphenyl-4-yl)-methyl]-4-hydroxy-2-methylmercapto-6-propylpyrimidine prepared above are dissolved in 370 ml of 2-methoxyethanol. 33 ml of hydrazine hydrate are added and the mixture is then refluxed for 3 h. It is concentrated under vacuum, taken up in acetonitrile and triturated. The solid obtained is filtered off and washed with ether and isopropyl ether to give 9.9 g of 5-[(2'-cyanobiphenyl- 4-yl)methyl]-2-hydrazino-4-hydroxy-6-propylpyrimidine.
