Conditions

Temperature: 90 °C

Procedure

In dried vial with a Teflon lined screw cap, a solution of Compound 482 (156 mg, 0.31 mmol), 4-chlorophenylboronic acid (73 mg, 0.465 mmol), and Palladium Tetrakis (37 mg, 0.031 mmol) in toluene (9 mL), methanol (2 mL), and saturated sodium bicarbonate in water (900 μL) was degassed, flushed with argon, and sealed. The reaction was stirred for 16 h at 90° C. The completed reaction was then evaporated to dryness, purified via HPLC, and converted to the HCl salt using the standard procedure (as described in Compound 516) to produce the title compound (73 mg, 42% yield).
