HCID 8028TetrahydrofuranSolvent

Procedure

In 30 mL of tetrahydrofuran was dissolved 620 mg of 4-(3-chloro-4-(3-fluorobenzyloxy)phenylamino)-6-formylquinazoline (IV-1), the solution was cooled to 0° C. under the nitrogen atmosphere, and 4.9 mL of methylmagnesium bromide (0.93M tetrahydrofuran solution) was added dropwise. After the reaction at 0° C. for 1 hour under the nitrogen atmosphere, water and ethyl acetate were added to separate the layers. The organic layer was washed sequentially with water and aqueous saturated sodium chloride solution, and dried over magnesium sulfate. After concentration, the resulting crystal was washed with chloroform to obtain 330 mg of 4-(3-chloro-4-(3-fluorobenzyloxy)phenylamino)-6-(1-hydroxyethan-1-yl)quinazoline (VI-1).
