Reaction Steps

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(dppf)Cl2 (about 5 mol %), and CuI (about 6 mol %) in dry THF (0.5 mL) followed by 3-methylbutyl zinc bromide (0.273 mL, 0.138 mmol (0.5M in THF)) dropwise. The solution was heated in the microwave for 10 minutes at 160° C., filtered, and was purified by Prep HPLC to give 6.2 mg (25%) of the desired compound as the TFA salt.
