Reaction Steps

7-Chloro-3,4-dihydroisoquinolin-1(2H)-one (I-1d: 100 mg, 0.552 mmol) was reacted with 3-bromo-4-ethyl pyridine (133.5 mg, 0.718 mmol), 1,4-dioxane (5 mL), copper iodide (10.48 mg, 0.0555 mmol), trans-N,N′-dimethyl-cyclohexyl-1,2-diamine (7.8 mg, 0.055 mmol) and potassium phosphate (351 mg, 1.657 mmol for 48 hours at 120° C. to afford the crude product. Purification by column chromatography on silica gel (50% ethyl acetate in hexane), followed by preparative HPLC afforded 25 mg of the product (15.72% yield).
