Reaction Steps

A mixture of N-(4-methylphenyl)-2-(1-piperazinyl)-6-(1-piperidinyl)-4-pyrimidinamine (100 mg, 0.284 mmol), 2-bromo-3-methylpyridine (54 mg, 0.312 mmol), 1,1′-(bisdiphenylphosphino)-1,1′-binaphthol (13 mg), tris(dibenzylidene acetone)dipalladium(0) (13 mg), and sodium tert-butoxide (136 mg) in dry toluene (4 mL) was heated at 90° C. in a sealed tube for 2 hours. The reaction was quenched with water and the solution was extracted three times with ethyl acetate. The solvent was dried and removed. The crude material was purified by preparative TLC, eluting with hexane/ethyl acetate (2:1). N-(4-methylphenyl)-2-[4-(3-methyl-2-pyridinyl)-1-piperazinyl]-6-(1-piperidinyl)-4-pyrimidinamine was obtained, from the band at Rf=0.46, as a solid (17.1 mg, 0.0385 mmol, 14%).
