Reaction Steps
In analogy to the procedure described in example 20b, 4-chloro-2,6-bis-(2-hydroxy-ethylamino)-pyrimidine-5-carbonitrile was treated with 1-(o-tolyl)-piperazine dihydrochloride in dioxane in the presence of N-ethyl-diisopropylamine at 80° C. to yield 2,4-bis-(2-hydroxy-ethylamino)-6-(4-o-tolyl-piperazin-1-yl)-pyrimidine-5-carbonitrile as an amorphous, light brown solid; MS: [M+H]+=398.
