Reaction Steps

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 (100 mg, 0.204 mmol), 3-(trifluoromethyl)-1H-pyrazole (55.4 mg, 0.407 mmol), (1R,2S)—N1,N2-dimethylcyclohexane-1,2-diamine (5.79 mg, 0.041 mmol), copper(I) iodide (19.38 mg, 0.102 mmol) and potassium carbonate (84 mg, 0.611 mmol) in dioxane (1 mL) was heated up at 100° C. for 36 hours. LCMS indicated desired product was formed. The reaction mixture was filtered and the clear solution was dissolved in methanol and purified by prep. HPLC to give 1-(4-methoxy-7-(3-(trifluoromethyl)-1H-pyrazol-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 white solid (37 mg, 32%).
