Procedure

Part B: A mixture of the product from part A (1.09 g), 2-bromo-4-isopropylphenylguanidine hydrochloride (1.17 g), and sodium carbonate (424 mg) in 2-methoxyethanol (30 mL) was refluxed for 19 hr. The cooled reaction mixture was diluted with ethyl acetate and washed with water (2×) and brine, dried and evaporated. The crude reaction product was chromatographed on silica gel using 50% petroleum ether in methylene chloride as eluent. The intermediate anilinopyrimidine was obtained as an oil (337 mg). CI Mass Spec. (M+H)+ =462.
