A mixture of methyl 2-iodo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine-10-carboxylate (370.1 mg, 1.000 mmol), 1-isopropyl-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole (354 mg, 1.50 mmol), [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex with dichloromethane (1:1) (40.8 mg, 0.0500 mmol) and 2.0 M of Potassium acetate in water (1.00 mL) in Acetonitrile (12 mL, 230 mmol) was degassed. The reaction was microwaved on 200 watts, 140° C. for 30 minutes. The reaction mixture was partitioned between water and ethyl acetate, filtered, the organic layer was washed with water, brine, dried over MgSO4 and concentrated in vacuum. The residue was purified on 12 g silica column eluting with 35-40% ethyl acetate in heptane. Yield 119 mg (34%). MS: (ESI+): 353.1.
