Participants

Reaction Steps

7-Chloro-3,4-dihydroisoquinolin-1(2H)-one (I-1d: 100 mg, 0.552 mmol) was reacted with 4-cyclopropyl-3-iodopyridine (I-73c: 162 mg, 0.662 mmol), 1,4-dioxane (5 mL), copper iodide (31 mg, 0.165 mmol), trans-N,N′-dimethyl-cyclohexyl-1,2-diamine (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 (2% methanol in CHCl3) afforded 42 mg of the product (25.45% yield).
