Versuchsvorschrift

Using an analogous procedure and workup as described for the preparation of Example 1A above, 6,7-dichloro-3,4-dihydroisoquinolin-1(2H)-one (I-55d: 100 mg, 0.463 mmol) was reacted with 3-bromo-4-(trifluoromethyl)pyridine (115 mg, 0.509 mmol), 1,4-dioxane (3 mL), copper iodide (7 mg, 0.046 mmol), trans-N,N′-dimethyl-cyclohexyl-1,2-diamine (20 mg, 0.1388 mmol) and potassium phosphate (245 mg, 1.157 mmol) in a sealed tube at 120° C. for 16 hours to afford the crude product. Purification by column chromatography on silica gel (20% ethylacetate in hexane) afforded 14 mg of the product (8.3% yield).
