Thionyl chloride (1.887 g, 1.157 mL, 15.86 mmol) was added to a solution of 3-amino-6-(4-ethylsulfonylpiperazin-1-yl)pyrazine-2-carboxylic acid (1.25 g, 3.964 mmol) in chloroform (50 mL) and DMF (1 mL) and the resulting dark solution heated under reflux for 1 hour. The reaction mixture was allowed to cool to RT, concentrated in vacuo and taken through crude to the next stage.
