Participants

Reaction Steps

Ethylmagnesium bromide in ethyl ether (3.0 M, 0.104 mL, 0.31 mmol)) was added dropwise to a suspension of methyl 9,10-diiodo-6,7-dihydroimidazo[1,2-d]pyrido[3,2-b][1,4]oxazepine-3-carboxylate (130 mg, 0.26 mmol) in Tetrahydrofuran (5.0 mL, 62 mmol) at −15° C. The mixture was stirred for 15-20 min (a completion was monitored by LCMS), pour into 20 ml of sat. aq. NH4Cl and extracted with ethyl acetate. The organic extracts were washed with water (2×20 ml), brine, dried over MgSO4 and concentrated in vacuum. Weight 92 mg (94%). MS (ESI+): 372.0.
