実験手順

A mixture of 6-fluorospiro[isobenzofuran-1(3H),4′-piperidine]-3-one hydrochloride (64 mg), phenyl N-(5-phenyl-2-pyrazinyl)carbamate (73 mg) and triethylamine (174 μL) in chloroform (5 mL) was stirred at 80° C. for 2 hours. The reaction mixture was poured into water and extracted with chloroform (20 mL). The organic layer was washed with saturated saline solution (20 mL), then dried over anhydrous Na2SO4 and concentrated. The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=4/1 to 1/2) and recrystallized from ethyl ether-hexane to give the subject compound (101 mg) as colorless crystals (melting point 222-224° C.).
