In dried vial with a Teflon lined screw cap, a solution of Compound 365b (100 mg, 0.175 mmol), 4-fluoro-3-chlorophenylboronic acid (61 mg, 0.2625 mmol), and Palladium Tetrakis (20 mg, 0.0175 mmol) in toluene (6.5 mL), methanol (1.6 mL), and saturated sodium bicarbonate in water (800 ul) was degassed, flushed with argon, and sealed. The reaction was stirred for 16 hours at 90° C. The vial was then cooled to room temperature and 10% w/v KOH in methanol (2 mL, 3.5 mmol) was added. The reaction was resealed and stirred at 70° C. for 1 hour. The completed reaction was then evaporated to dryness, purified via HPLC, and converted to the HCl salt using the standard procedure (as described for Compound 516) to produce the title compound (7 mg, 7% yield).
