Versuchsvorschrift

Preparation analogous to 16), S43, using 16.1 g (100 mmol) of 2-tert-butyl-5-cyanopyrimidine [126230-72-6] and 71.4 g (300 mmol) of 3,4-diamino-6-tert-butylpyridine dihydrochloride (S50) instead of 25.9 g (100 mmol) of 2-N-pivaloylamido-3-cyano-6-tert-butylpyridine (S42) and 90.5 g (500 mmol) of o-phenylenediamine dihydrochloride [615-28-1]. After cooling, the violet melt is dissolved in a mixture of 150 ml of ethanol and 300 ml of water at elevated temperature, and a solution of 25 g of sodium carbonate in 100 ml of water is then added dropwise with vigorous stirring (note: foaming, evolution of carbon dioxide). When the addition is complete, the mixture is stirred for a further 30 min., the brown solid is then filtered off with suction, washed three times with 100 ml of water each time and dried in vacuo. Yield: 23.8 g (77 mmol), 77%. Purity: >95% according to 1H-NMR.
