In analogy to the procedure described in example 47b, the crude 4-chloro-6-(2-hydroxy-ethylamino)-2-[(pyridin-3-ylmethyl)-amino]-pyrimidine-5-carbonitrile (example 49a) was treated with 1-(4-fluorophenyl)-piperazine in dioxane in the presence of N-ethyl-diisopropylamine at 90° C. to yield 4-[4-(4-fluoro-phenyl)-piperazin-1-yl]-6-(2-hydroxy-ethylamino)-2-[(pyridin-3-ylmethyl)-amino]-pyrimidine-5-carbonitrile as an amorphous, light brown powder; MS: [M+H]+=449.
