Procedure
2-Benzyl-1′-tert-butoxycarbonylspiro[1H-isoindole-1,4′-piperidine]-3(2H)-one (200 mg) was added to metallic sodium (235 mg) in liquid ammonia (10 mL) and the mixture was stirred for 30 minutes. To the reaction mixture was added methanol, neutralized with a saturated ammonium chloride aqueous solution and extracted with ethyl acetate. The organic layer was dried over anhydrous Na2SO4 and concentrated. The residue dissolved in methanol was stirred together with 4M hydrogen chloride/ethyl acetate at 50° C. for 1 hour. The reaction solution was concentrated to give the subject compound (591 mg).
