Reaction Steps

6-Chloro-3,4-dihydro-2H-isoquinolin-1-one (intermediate A-2) (36 mg, 0.2 mmol), 5-bromo-nicotinonitrile (73 mg, 0.4 mmol), CuI (3.8 mg, 0.02 mmol), (1S,2S)-cyclohexane-1,2-diamine (4.5 mg, 0.04 mmol) and Cs2CO3 (130 mg, 0.4 mmol) were dissolved in dioxane (5 mL). The reaction mixture was subjected to microwave reaction at 150° C. for 2.5 hours before it was poured into H2O (50 mL) and extracted with EtOAc (2×25 mL). The organic layer was washed with brine, dried over anhy. Na2SO4, filtered and concentrated in vacuo to give a crude product which was purified by prep-HPLC to yield the title compound (15 mg, 26%) as a white solid. MS: 284.1 (M+H+).
