실험 절차

(Method C) 4-(6-Chloronaphthalene-2-sulfonyl)-1-[1-(4-pyridyl)-4-piperidinylamino]-2-piperazinone (90 mg) was dissolved in a 37% aqueous solution of formaldehyde (2.9 ml) and formic acid (1.4 ml) and refluxed for 15 hours. The reaction mixture was cooled, made alkaline by adding a 1N aqueous solution of sodium hydroxide, extracted with dichloromethane, dried and concentrated. The residue obtained was purified by a column chromatography (dichloromethane: 10% aqueous ammonia-containing methanol=20:1) to obtain the title compound (38 mg) as colorless crystals.
