3,5-Diamino-6-chloro-N-[(methylsulfanyl)methanimidoyl]pyrazine-2-carboxamide (Intermediate 3, 250 mg, 0.88 mmol) is dissolved in tetrahydrofuran (20 mL) and to the solution 3-amino-quinuclidine dihydrochloride (211 mg, 1.06 mmol) and triethylamine (0.61 mL, 4.41 mmol) are added. The mixture is heated at 80° C. for 24 hours. The solid is removed by filtration and the is filtrate evaporated and purified by preparative HPLC (5 mM ammonium formate in H2O: CH3CN gradient) obtaining the title compound (45 mg).
