Reaction Steps

3-[(1S)-2-Methoxy-1-methylethoxy]-5-{5-[(5S)-5-methyl-4,5-dihydro-1,3-oxazol-2-yl]-1H-pyrrol-2-yl}phenol (40 mg, 0.12 mmol) synthesized in Example (116d) and 1-[(4-fluorophenyl)sulfonyl]-4-methylpiperazine (25 mg, 0.15 mmol) synthesized in Example (116a) were dissolved in N,N-dimethylformamide (2 mL), and potassium carbonate (51 mg, 0.37 mmol) was added, followed by stirring at 100° C. for 1 hour under nitrogen atmosphere. 1-[(4-Fluorophenyl)sulfonyl]-4-methylpiperazine (30 mg) was added again, and the mixture was stirred at 90° C. overnight. The reaction solution was cooled to room temperature, water (10 mL) was added, and extraction was carried out twice with ethyl acetate (10 mL). The organic layer was washed with saturated brine, and subsequently dried over anhydrous magnesium sulfate. The solvent was distilled off under reduced pressure, and the resulting residue was purified using silica gel column chromatography (elution solvent: methanol/methylene chloride=0%-5%) to afford the desired compound (25 mg, yield 35%) as a white solid.
