SPECIFIC COMPOUNDS - 385 Compounds (I) are disclosed e.g. N-(4-cyclopropylamino-6-(2,4-dichloro-phenyl)-pyrimidin-5-yl)-2-ethyl-nicotinamide of formula (Ia), N-(4-(4-chloro-phenyl)-6-cyclopropylamino-pyrimidin-5-yl)-2-ethyl-nicotinamide, N-(4-chloro-6-((4-(trifluoromethyl)phenyl)amino)pyrimidin-5-yl)-2-ethylnicotinamide, N-(4-cyclopropylamino-6-(2,4-difluoro-phenyl)-pyrimidin-5-yl)-2-ethyl-nicotinamide and N-(4-cyclopropylamino-6-(3,4-difluoro-phenyl)-pyrimidin-5-yl)-2-ethyl-nicotinamide.    EXAMPLE - 6-Chloro-N-cyclopropyl-pyrimidin-4,5-diamine (3 g) was added in a mixture of methyl chloride (12.20 ml) and pyridine (3.94 ml). The above suspension was cooled at 0 degrees C and further 2-ethylnicotinoylchloride (1.2 equivalents) was added and stirred. Then methyl chloride (10 ml) was added and the obtained organic phase was treated with partially saturated sodium bicarbonate solution (approximately 10 ml), strongly stirred and washed thrice with n-heptane and dried to obtain N-(4-chloro-6-cyclopropylamino-pyrimidin-5-yl)-2-ethyl-nicotinamide (3.41 g). N-(4-Chloro-6-cyclopropylamino-pyrimidin-5-yl)-2-ethyl-nicotinamide (0.41 mmole), sodium carbonate (3 equivalent) and 2,4-dichlorophenylboronic acid (2 equivalent) were reacted with degassed diluent mixture of dioxane (2 ml)/water (0.7 ml) and heated at 100 degrees C. Then tetrakis(triphenylphosphine)palladium(0) (5 mol.%) was added to the mixture and stirred for 3 hours at 90 degrees C. The obtained mixture was diluted with water and extracted thrice with methyl chloride. The organic phase was washed with aqueous sodium bicarbonate solution and worked up to obtain N-(4-cyclopropylamino-6-(2,4-dichloro-phenyl)-pyrimidin-5-yl)-2-ethyl-nicotinamide.
