Reaction Steps

A mixture of 5-bromo-6-chloro-3-methoxy-2-pyrazinamine (Example 125a) (0.6 g), triethylamine (0.72 mL), 10% palladium on carbon (0.05 g) and ethyl acetate (50 mL) were hydrogenated at 0.5 bar until reaction was complete as judged by hydrogen uptake. The reaction mixture was filtered and washed with water (25 mL), dried (MgSO4), filtered and evaporated to afford the sub-titled compound (0.33 g). Used Directly.
