실험 절차

A solution of 3-amino-6-bromo-pyridine-2-carboxylic acid ethyl ester (40 mg, 163 μmol) and copper(I) cyanide (29.2 mg, 326 μmol) in DMF (800 μL) was heated in the microwave at 220° C. for 8 min. The reaction mixture was filtered through diatomaceous filter-aid and the crude product was purified by preparative HPLC to afford the title compound as off-white solid (8.3 mg, 26.6%).
