Reaction Steps

Under Ar, a suspension of the product from Example 9, Step 2 (18.9 mg, 61.1 μmol) in DMF (1 mL) was treated with benzylamine (12 μl, 110 μmol), copper iodide (2.3 mg, 12.2 μmol), phenyl 2-hydroxybenzoate (6.6 mg, 30.6 μmol), and potassium carbonate (16.9 mg, 122.2 μmol). This mixture was then heated to 170° C. by microwave for 40 min. After cooling rt, the reaction mixture was diluted with ethyl acetate and washed with water and brine. The organic layer was dried over Na2SO4, filtered and concentrated in vacuo. The residue was purified by reverse phase HPLC to give the title compound (2.6 mg, 10%). MS (ES+) m/e 336 [M+H]+.
