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 as basified with 10 N 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°.
