実験手順

Diethyl azodicarboxylate (261 mg, 1.5 mmol) was added dropwise to a mixture of 4-(4-chloro-2-fluoroanilino)-7hydroxy-6-methoxyquinazoline (160 mg, 0.5 mmol), (prepared as described for the starting material in Example 2), triphenylphosphine (393 mg, 1.5 mmol) and 1-(3-hydroxypropyl)-2-pyrrolidinone (107 mg, 0.75 mmol) in methylene chloride (5 ml) under nitrogen. The mixture was stirred for 20 minutes at ambient temperature and then purified by pouring directly onto a column of silica eluting with methylene chloride/ethyl acetate/methanol (60/35/5 followed by 60/30/10). The purified product was triturated with ether and collected by filtration. The solid was dissolved in ethyl acetate and treated with 3M hydrogen chloride in ethyl acetate (0.4 ml). The precipitate was collected by filtration, washed with ethyl acetate and dried under vacuum to give 4-(4-chloro-2-fluoroanilino)-6-methoxy-7-(3-(2-oxopyrrolidin-1-yl)propoxy)quinazoline hydrochloride (170 mg, 70%).
