반응 단계

Sodium methoxide (70 mg, 1.29 mmol) was added to a stirred solution of 5-amino-3-chloropyrazine-2-carbonitrile (100 mg, 0.647 mmol) in dioxane (1 mL). The reaction mixture was heated in a sealed tube at 90° C. overnight. The solvent was removed in vacuo, and the residue was partitioned between water and ethyl acetate. The aqueous layer was re-extracted with ethyl acetate. The combined organic layers were washed with brine, dried (Na2SO4) and concentrated to give the title compound (32 mg, 0.213 mmol, 33%). LC-MS (3) Rt=0.96 min; m/z (ESI+) 151 (M+H+).
