実験手順

To a suspension of 6-ethylspiro[isobenzofuran-1(3H),4′-piperidine]-3-one hydrochloride (53 mg) and phenyl N-(5-phenyl-2-pyrazinyl)carbamate (58 mg) in dimethyl sulfoxide (1 mL) was added 10 M sodium hydroxide aqueous solution (0.02 mL). The mixture was vigorously stirred for 5 minutes followed by partition between water and ethyl acetate. The organic layer was separated and then washed with saturated saline solution and then dried over anhydrous Na2SO4. The concentration of the organic solvent left a residue, which was subjected to the crystallization from ethyl acetate to give the subject compound (46 mg) as crystals (melting point 176-178° C.).
