Procedure

A solution of the compound of Example 77 (300 mg, 0.64 mmol), 4-fluorobenzonitrile (115 mg, 0.95 mmol) and potassium carbonate (176 mg, 1.3 mmol) in N-methylpyrrolidone (3.0 mL) was stirred at 120° C. for 16.5 hr. The reaction mixture was diluted with water, and extracted twice with ethyl acetate. The extract was washed with brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by aminosilica gel chromatography (eluate; ethyl acetate/hexane=30/70-100/0) and recrystallized from THF-diethyl ether to give the title compound (73 mg, 20%) as a pale-yellow solid.
