实验步骤: A solution of 4,6-dichloro-pyrimidine-5-carbonitrile Compound 2a (82 mg, 0.47 mmol), Et3N (0.13 mL, 0.94 mmol) and 4-benzyloxy-3-chloro-phenylamine Compound 2b (110 mg, 0.47 mmol) in THF (4.7 mL) was stirred at 25° C. for 3 hours. The reaction mixture was diluted with EtOAc (50 mL), washed with water (1×50 mL) and concentrated to afford 4-(4-benzyloxy-3-chloro-phenylamino)-6-chloro-pyrimidine-5-carbonitrile Compound 2c (175 mg, 100%) as an off-white solid; 1H NMR (300 MHz, CD3OD) δ 8.42 (s, 1H), 7.63 (s, 1H), 7.52-7.40 (m, 7H), 7.12 (m, 1H), 5.22 (s, 2H), 5.19 (s, 2); MS (ESI) m/z: 373 (MH+). washed with water (1×50 mL) concentrated

实验步骤: A mixture of 4.17 g (0.0149 moles) of the N-(4-chloro-3-cyano-7-ethoxy-6-quinolinyl)acetamide, 4.04 g (0.0173 moles) of 4-benzyloxy-3-chloro-phenylamine (example 5), and 2.0 g (0.017 moles) of pyridine hydrochloride in 85 ml of isopropanol was stirred and refluxed in an oil bath for 30 minutes. The reaction was cooled in an ice bath, and the solid was collected by filtration and washed with isopropanol, and then with ether yielding 7.26 g of crude product as the hydrochloride salt. This material was purified by chromatography of the free base on silica gel by elution with 1:39 methanol-methylene chloride. refluxed in an oil bath for 30 minutes The reaction was cooled in an ice bath the solid was collected by filtration washed with isopropanol This material was purified by chromatography of the free base on silica gel by elution with 1:39 methanol-methylene chloride

实验步骤: A mixture of 6.59 g (0.025 moles) of the 4-benzyloxy-3-chloro nitrobenzene (example 4), 4.19 g (0.075 moles) of iron powder, and 12.04 g (0.225 moles) of ammonium chloride in 100 ml of ethanol and 25 ml of water was stirred mechanically and refluxed for half an hour. The reaction was allowed to cool and stir for 1 hour. The mixture was filtered and solids were washed with ethanol. The combined filtrates were taken to dryness in vacuo. This solid was dissolved in methylene chloride and passed through Magnesol. Removal of the solvent from the filtrate in vacuo gave 5.60 g of title compound. refluxed for half an hour to cool stir for 1 hour The mixture was filtered solids were washed with ethanol This solid was dissolved in methylene chloride Removal of the solvent from the filtrate in vacuo
