Reaction Steps

9-fluoro-2,3-diiodo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (1.24 g, 2.74 mmol) was dissolved in tetrahydrofuran (25 mL, 310 mmol) and cooled to −78° C. in a dry ice/acetone bath. Added 3.0 Methylmagnesium bromide in ether (1.37 mL and allowed the reaction to warm up to −40° C. and stir for 4 hours. Complete by LCMS. Diluted with 100 mL of saturated ammonium chloride and extracted with ethyl acetate. Dried over magnesium sulfate, concentrated in vacuo and purified by flash chromatography on the ISCO 0-40% ethyl acetate in hexanes to give 9-fluoro-2-iodo-5,6-dihydrobenzo[f]imidazo[1,2-d][1,4]oxazepine (0.794 g, 88% yield)
