Procedure

Methyl 2-iodo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-9-carboxylate (80 mg, 1 eq), 2-ethylphenylboronic acid (60 mg, 1.75 eq), and tetrakis(triphenylphosphine)palladium (10 mg, 0.05 eq), in 1.0 M aqueous sodium carbonate (1.0 mL) and acetonitrile (1.0 mL) were heated to 140° C. for 10 min in a sealed microwave reactor. The crude reaction mixture was concentrated and purified using reverse phase HPLC to yield 297 (11 mg). ESI-MS: 349.1 (M)+
