Procedure
A mixture of 2.4 g 4-(4-bromo-1-trityl-1H-pyrazol-3-yl)phenylamine (compound in Production Example 152), 0.7 mL 2-bromoethyl ether, 80 mg sodium iodide, 1.52 g potassium carbonate and 50 mL N,N-dimethylformamide was stirred at 80° C. for 3 days. Ethyl acetate and water were added to the reaction solution, then water was added thereto, and the organic layer was separated, washed with an aqueous saturated solution of sodium bicarbonate, water and brine and dried over anhydrous sodium sulfate. The drying agent was filtered off, and the filtrate was evaporated. The resulting residue was purified by NH silica gel column chromatography (ethyl acetate/hexane) to give 1.21 g of the title compound as a pale yellow amorphous.
