Procedure
A mixture of 4-[2-(2,2,2-trifluoroethyl)guanidino]-2-(3-aminopropylthio)pyrimidine (0.3 g.), ethyl formate (5 ml.) and EtOH (2 ml.) was heated under reflux for 48 hours, then evaporated to dryness. The residue was dissolved in N aqueous HCl and the solution washed with EtOAc. The aqueous phase was basified with 10N aqueous NaOH, extracted with EtOAc and the extract dried and evaporated to dryness. The residue was recrystallised from EtOAc to give N-[3-(4-[2-(2,2,2-trifluoroethyl)guanidino]pyrimid-2-ylthio)propyl]formamide (0.2 g.), m.p. 165°-166°.
