Reaction Steps

4-[(4-chloro-2-pyrimidinyl)amino]benzonitrile (0.003 mol), 2,6-dibromo-4-methyl-benzenamine (0.006 mol) and 1 M HCl in diethyl ether (4.5 ml) in 1,4-dioxane (10 ml) were combined in a tube and heated under Ar until all diethyl ether had evaporated. The tube was sealed and heated at 170° C. for 2.5 days. Silica gel was added, and the solvent was evaporated. The residue was purified by flash column chromatography over silica gel (eluent gradient: CH2Cl2:CH3OH:NH4OH 100:0:0 to 99:0.9:0.1). The desired fractions were collected and the solvent was evaporated. The residue was recrystallized from acetonitrile, filtered off and dried, yielding 0.22 g (15.9%) of 4-[[4-[(2,6-dibromo-4-methylphenyl)amino]-2-pyrimidinyl]amino]benzonitrile (compound 61).
