Reaction Steps

A mixture of 70 mg (0.27 mmol) of 4-chloro-2-cyclopropylamino-6-(2-hydroxy-ethylamino)-pyrimidine-5-carbonitrile and 0.047 ml (0.27 mmol) of N-ethyl-diisopropylamine in 5 ml of dioxane was treated with 49 mg (0.3 mg) of 1-phenyl-piperazine. The solution was heated to 100° C. during 18 hours, thereafter, for the working-up, evaporated under reduced pressure. For purification, the residue obtained was chromatographed by preparative HPLC on RP18-silica gel using a gradient of a mixture of acetonitrile and water (plus 0.1% of formic acid) as the eluent to give 60 mg (0.16 mmol, 58% of theory) of the 2-cyclopropylamino-4-(2-hydroxy-ethylamino)-6-(4-phenyl-piperazin-1-yl)-pyrimidine-5-carbonitrile as a white powder after lyophilization; MS: [M+H]+=380.
