実験手順
Di-tert-butyl azodicarboxylate (1.44 g, 6.26 mmol) was added portionwise at room temperature to a stirred suspension of 4-chloro-7-methoxyquinazolin-6-ol (1.20 g, 5.70 mmol), 3-morpholin-4-ylpropan-1-ol (0.91 g, 6.27 mmol) and triphenylphosphine (1.8 g, 6.87 mmol) in dichloromethane (25 ml). The reaction mixture was stirred for 2 hours and then the resulting orange solution was purified directly by silica gel chromatography eluting with a mixture of 5% methanol in dichloromethane to give 4-chloro-7-methoxy-6-(3-morpholin-4-ylpropoxy)quinazoline (1.28 g, 67% yield) as a pale yellow solid:
