Into a dry microwave vial under N2 was added 6-bromo-4-[1-(3-phenyl-allyl)-piperidine-4-ylamino]-chromen-2-one (20 mg, 0.046 mmol), Pd(PPh3)Cl2 (about 1 mol %), and Cs2CO3 (17.8 mg, 0.0547 mmol) in DME/H2O/EtOH (7/3/2, 0.5 mL). Phenyl boronic acid (5.6 mg, 0.046 mmol) was added and the solution was heated in the microwave for 5 minutes at 160° C., filtered, and was purified by Prep HPLC to give 5.86 mg (23%) of the desired compound as the TFA salt.
