실험 절차

A mixture of 4-[3-(2,2,2-trifluoroethyl)thioureido]-[(3-phthalimido)propylthio]pyrimidine (0.4 g.), N,N,-dimethylformamide (5 ml.), saturated ethanolic ammonia (10 ml.) and yellow mercuric oxide (280 mg.) was stirred at room temperature for 3 hours and then filtered and the filtrate evaporated to dryness. A solution of the residue in ethanol (10 ml.) was treated with hydrazine hydrate (1 ml.), the mixture heated under reflux for 1 hour and then evaporated to dryness. The residue was stirred with 1 N hydrochloric acid and then filtered and the filtrate basified with 17 N NaOH. The mixture was extracted with ether and the combined ether extracts dried and evaporated to dryness to give 4-[2-(2,2,2-trifluoroethyl)guanidino]-2-[(3-amino)propylthio]-pyrimidine which was used without further purification.
