反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: Diethyl azodicarboxylate (209 mg, 1 mmol) was added dropwise to a mixture of 4-(4-chloro-2-fluoroanilino)-7-hydroxy-6-methoxyquinazoline (128 mg, 0.4 mmol), (prepared as described for the starting material in Example 2), cis-3-(2,6-dimethylmorpholino)-1-propanol (97 mg, 0.56 mmol) and triphenylphosphine (314 mg, 1.2 mmol) in methylene chloride (4 ml) under nitrogen. The mixture was stirred for 1 hour at ambient temperature and the solvent was removed by evaporation. The residue was purified by column chromatography eluting with methylene chloride/methanol (95/5 followed by 90/10). The purified product was dissolved in methylene chloride and 2M ethereal hydrogen chloride (1 ml) was added. The solution was diluted with ether and left to stand. The resulting precipitate was collected by filtration, washed with ether and dried under vacuum to give 4-(4-chloro-2-fluoroanilino)-7-(3-(2,6dimethylmorpholino)propoxy)-6-methoxyquinazoline hydrochloride (130 mg, 590%). (prepared the solvent was removed by evaporation The residue was purified by column chromatography eluting with methylene chloride/methanol (95/5 followed by 90/10) The purified product was dissolved in methylene chloride 2M ethereal hydrogen chloride (1 ml) was added The solution was diluted with ether left The resulting precipitate was collected by filtration washed with ether dried under vacuum

实验步骤: 3-Chloro-1-propanol (1.04 g, 11 mmol) followed by potassium carbonate (2.07 g, 15 mmol) was added to a solution of 2,6-dimethylmorpholine (1.15 g, 10 mmol), (supplied by Aldrich Chemical Company Limited as a mixture of isomers), in acetonitrile (15 ml). The mixture was heated at reflux overnight and allowed to cool, the insolubles were removed by filtration and the volatiles were removed from the filtrate by evaporation. The residue was purified by column chromatography on silica eluting with methylene chloride/acetonitrile/methanol (60/35/5 followed by 60/30/10) to give cis-3-(2,6-dimethylmorpholino)-1-propanol (500 mg).
