Procedure

2.0 M of Isopropylmagnesium Chloride in tetrahydrofuran (0.782 mL) was added dropwise to a solution of 0.644 g (1.36 mmol) of 9-chloro-2,3-diiodo-5,6-dihydroimidazo[1,2-d]pyrido[3,2-f][1,4]oxazepine in 12 ml of tetrahydrofuran at −10° C. The mixture was allowed to warm to 15° C. The mixture then was quenched by addition of 20 ml of sat. aqueous NH4Cl and extracted with ethyl acetate. The organic extracts were washed with water, brine, dried over Na2SO4 and concentrated to give 9-chloro-2-iodo-5,6-dihydroimidazo[1,2-d]pyrido[3,2-f][1,4]oxazepine. Yield 448 mg (98%). M/z 348.2, calc. M 346.93. 1H NMR (400 MHz, CDCl3) δ 8.83 (d, J=8.2, 1H), 7.16 (dd, J=14.0, 5.9, 1H), 7.10 (s, 1H), 4.61-4.54 (m, 2H), 4.41 (dd, J=5.0, 2.9, 2H)
