实验过程
13.9 g of 1,3-bis-(3,5-dibromo-4-nitropyrazol-1-yl-methyl)benzene from step 4.1 are heated together with 6.5 g of benzylamine in 130 ml of n-propanol for 2 hours at 95° C. Subsequently the reaction mixture is cooled and poured into 400 ml water. The precipitate is filtered with suction and recyrstallized from 150 ml of acetonitrile.
