Reaction Conditions

Reaction Steps

To a solution of 2-aminopyrazine (1.87 g) in dry acetone (30 ml) was added potassium carbonate (3 eqv), 4-bromoacetyl pyridine (2 eqv) and the resulting reaction mixture was heated at 60° C. for 20 hrs. Reaction mixture was filtered through a celite bed, residue washed with DCM and combined organic layer was evaporated completely to get a brown residue. It was again dissolved in ethyl acetate, washed with water and brine and finally dried over sodium sulfate. Evaporation of organic layer gave the crude product which was purified by column chromatography (1% methanol in dichloromethane). Yield: 12%, 30% Starting material recovered.
