الإجراء التجريبي

A solution of 1.43 g (10 mmol) 3-chloro-2-methyl-phenol and 0.4 g sodium hydride (60% in paraffine, 10 mmol) in 20 ml THF were stirred for 30 min at ambient temperature. After adding 1.25 g (5 mmol) 4-(2-chloro-pyrimidin-4-yloxy)-2,5-dimethyl-phenylamine the mixture was stirred for 20 hrs at 60° C. After cooling down to ambient temperature 20 ml water was added and the organic layer was separated, dried over magnesium sulfate, concentrated in vacuo, column chromatography (cycclhexane/ethyl acetate, 2:1) and a second column chromatography (dichloromethane) yielded 640 mg (30%) with a purity of 85%; log P (pH=2.3)=2.81.
