Procedure
596 mg of methyl 4-({4,5-dimethyl-2-[(pyridin-2-ylsulfonyl)amino]phenoxy}methyl)benzoate was dissolved in 5.96 mL of DMF, and 820 mg of {[(2S)-3-bromo-2-methylpropyl]oxy}(tert-butyl)diphenylsilane and 1.37 g of cesium carbonate were added thereto, followed by stiffing at 80° C. for 4 hours. To the reaction liquid was added water, followed by extraction with ethyl acetate. The organic layer was washed with water and saturated brine, and then dried over anhydrous sodium sulfate. The solvent was evaporated and the obtained residue was purified by silica gel column chromatography (hexane:ethyl acetate=60:40) to obtain 840 mg of methyl 4-[(2-{[(2R)-3-{[tert-butyl(diphenyl)silyl]oxy}-2-methylpropyl](pyridin-2-ylsulfonyl)amino}-4,5-diphenylphenoxy)methyl]benzoate.
