5,5-Dimethyl-8-nitro-1,3,4,5-tetrahydro-benzo[b]azepin-2-one (4.00 g, 0.0171 mol) in Methylene chloride (54 mL, 0.84 mol) was cooled to 0° C., treated with TMEDA (7.73 mL, 0.05 mol) then treated dropwise with TMSI (7.29 mL, 0.05 mol). The mixture was stirred at 0° C. for 60 min after which solid Iodine (6.50 g, 0.0256 mol) was added in one portion and the mixture stirred at 0° C. for 60 min. The reaction was quenched with 10% Na2S2O3. Title compound isolated as a beige solid. (5.43 g, 88%) LCMS 361 (M+H).
