Reaction Steps

A mixture of sodium cyanide (21 mg, 0.42 mmol) and copper (I) cyanide (38 mg, 0.42 mmol) in anhydrous dimethylformamide (1.5 mL) was heated to 120° C. 3-Bromo-6-(2-furyl)-5-pyridin-4-ylpyrazin-2-amine (Example 62, 90 mg, 0.28 mmol) was added in portions. After stirring at 120° C. for two hours, the mixture was cooled and evaporated. A 0.75M aqueous solution of sodium cyanide (6 mL) was added, stirred for 10 min at room temperature and partitioned between water and ethyl acetate. The aqueous phase was extracted twice with ethyl acetate, the organic layers washed with brine, dried (MgSO4), and evaporated. Silica gel flash column chromatography (dichloromethane/methanol 98:2) furnished the title compound as a dark yellow solid (52 mg, 70%).
