Procedure

A mixture of 60 mg (0.27 mmol) 3,5-diamino-6-chloro-N[(methylsulfanyl)methanimidoyl]-pyrazine-2-carboxamide (intermediate 3) and 60 mg (S)-3-amino-1-benzyl-piperidine in 2 ml THF is stirred at 70° C. overnight. Then the reaction mixture is concentrated under reduced pressure and the residue is purified by preparative reverse phase HPLC (gradient of acetonitrile and water+0.2% trifluoroacetic acid, 25° C.). Fractions containing the title compound were concentrated under reduced pressure treated with excess HCl in methanol and evaporated again.
