Reaction Steps

To a solution of the compound (135 mg, 0.42 mmol) prepared in Example 13, 3-methoxyphenylboronic acid (96 mg, 0.63 mmol), potassium phosphate (2N, 1 mL 2.0 mmol), tetrakis(triphenylphosphine)palladium(0) (Pd(PPh3)4) (11 mg, 0.01 mmol) in dioxane (3 mL) was deoxygenated by nitrogen gas for 5 minutes, and the reactor was sealed, heated at 90° C. for 20 hours. The mixture was concentrated, extracted with DCM and sodium hydroxide (1N). The organic layer was dried, concentrated, and the crude product was purified by prep TLC using 9% methanol in DCM (with 1% ammonium hydroxide) to obtain the title compound (98 mg) having the following physical data.
