Procedure
1-(3,5-Diamino-6-chloro-pyrazine-2-carbonyl)-2-methyl-isothiourea (Intermediate A) (195 mg, 0.5 mmol) is suspended in propan-2-ol (10 ml) and (S)-2-(aminomethyl)pyrrolidine (100 mg, 1 mmol) is added. The mixture is heated at 60° C. for 18 hours, allowed to cool to room temperature and the precipitate is removed by filtration. The filtrate is concentrated in vacuo and the residue purified by chromatography (SiO2, DCM/MeOH) to afford the title compound as a light, yellow gum; [M+H]+ 296
