실험 절차

A solution of 3,4-dihydro-6-acetamido-1'-(4-aminobenzyl)spiro[(2H)-1-benzopyran-2,4'-piperidine](136 mg, 0.36 mmol) and hydrochloric acid (6N solution, 13. 6 ml) in methanol (13.6 ml) was heated at reflux temperature for 1 hr. The reaction mixture was cooled to 0° C. and basified with 20% sodium hydroxide solution. Extraction with methylene chloride, drying and solvent evaporation gave 3,4-dihydro-6-amino-1'-(4-aminobenzyl)spiro[(2H)-1-benzopyran-2,4'-piperidine]-4-one (107 mg, 88%);
