The solvent was evaporated and the residue was taken in 5 mL of DMF containing DIEA (258 mg, 2.0 mmol) and 2,6-dichloro-4-(1-pyrrolyl)pyrimidine (107 mg, 0.5 mmol). After heating overnight at 80° C., the reaction mixture was diluted with water and the product was extracted into ethyl acetate. The solvent was removed and the residue was chromatographed (silica gel, hexane:ethyl acetate (1:3)) to give 50 mg of the 2-(1-pyrrolyl)pyrimidine derivative and 58 mg of the 4-(1-pyrrolyl)pyrimidine compound 144, (M+H)+: 477.3
