After dissolving 114 mg of 1-(3-fluorophenyl)-3-{4-[6-(4-hydroxyphenyl)-7H-pyrrolo [2,3-d]pyrimidin-4-yloxy]phenyl}urea in 2 ml of dimethylformamide, there were added 44 mg (ca. 1 equivalent) of 2-chloroethyldiethylamine hydrochloride and 63 mg (2.5 equivalents) of potassium bicarbonate, and the mixture was stirred at 50-60° C. for 16 hours. There were then added 17 mg of 2-chloroethyldiethylamine hydrochloride, 20 mg of potassium bicarbonate and 1 ml of dimethylformamide, and the mixture was stirred overnight at the same temperature. It was then returned to room temperature, water was added, and liquid separation and extraction were performed with ethyl acetate-tetrahydrofuran. The organic layer was washed with water and saturated brine, concentrated and subjected to NH silica gel column chromatography (hexane-ethyl acetate) to obtain 33 mg of a crude solid containing the title compound. This was washed with ethyl acetate to obtain 5 mg of the title compound.
