Reaction Steps

5-Fluoro-N-methylpyridine-2-carboxamide (150 mg, 0.97 mmol) synthesized in Example (123a) and 3-{5-[(5R)-5-(hydroxylmethyl)-4,5-dihydro-1,3-oxazol-2-yl]-1H-pyrrol-2-yl}-5-[(1S)-2-methoxy-1-methylethoxy]phenol (438 mg, 1.27 mmol) synthesized in Example (125g) were dissolved in N,N-dimethylformamide (3 mL), and potassium carbonate (269 mg, 1.95 mmol) was added, followed by stirring at 100° C. for 3 hours under nitrogen atmosphere. The reaction solution was cooled to room temperature, water (30 mL) was added, and extraction was carried out twice with ethyl acetate (30 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 (281 mg, yield 60%) as a white solid.
