Versuchsvorschrift

To a suspension of ethyl 1-(2-benzyloxyethyl)-2-bromo-3-cyclohexyl-1H-pyrrolo[2,3-b]pyridine-6-carboxylate (592 mg, 1.22 mmol) and 2,4-bismethoxymethoxyphenylboronic acid (384 mg, 1.59 mmol) obtained in the same manner as in Example 2-1, Step 2 in 1,2-dimethoxyethane (12 ml) and water (6 ml) were added lithium chloride (155 mg, 3.66 mmol), sodium carbonate (388 mg, 3.66 mmol) and tetrakis(triphenylphosphine)palladium (141 mg, 0.12 mmol), and the mixture was stirred with heating at 110° C. for 2.5 hr. The reaction mixture was allowed to cool to room temperature. Water was added to the reaction mixture and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over anhydrous magnesium sulfate. After filtration, the solvent was evaporated under reduced pressure and the obtained residue was purified by silica gel chromatography (hexane:ethyl acetate=3:1) to give ethyl 1-(2-benzyloxyethyl)-2-(2,4-bismethoxymethoxyphenyl)-3-cyclohexyl-1H-pyrrolo[2,3-b]pyridine-6-carboxylate (727 mg, yield 99%).
