A mixture of 1-(7-bromo-4-methoxy-1H-pyrrolo[2,3-c]pyridin-3-yl)-2-(5-(pyridin-2-yl)-3,4-dihydroisoquinolin-2(1H)-yl)ethane-1,2-dione (80 mg, 0.163 mmol), 1H-1,2,4-triazole (45.0 mg, 0.651 mmol) and copper (20.69 mg, 0.326 mmol) in pyridine (1 mL) was heated at 145° C. for 10 hours, LCMS indicated the formation of desired product. The reaction mixture was filtered and the clear solution purified by prep. HPLC to give 1-(4-methoxy-7-(1H-1,2,4-triazol-1-yl)-1H-pyrrolo[2,3-c]pyridin-3-yl)-2-(5-(pyridin-2-yl)-3,4-dihydroisoquinolin-2(1H)-yl)ethane-1,2-dione as pale yellow solid (28 mg, 35%).
