Reaction Steps

To a solution of 1-Boc-hexahydro-1,4-diazepine (150 mg), 3-bromonitrobenzene (125 mg) and cesium carbonate (507 mg) in 1,4-dioxane (3 mL), bis[di-tert-butyl(4-dimethylaminophenyl)phosphine]dichloropalladium(II) (26 mg) was added at room temperature, and the mixture was stirred at 80° C. for 2 hours. The reaction mixture was cooled to room temperature, and then water and ethyl acetate were added to the mixture. The organic layer was separated, washed with saturated aqueous sodium chloride, and then dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (eluent, 100 to 70% hexane in ethyl acetate) to obtain tert-butyl 4-(3-nitrophenyl)-1,4-diazepane-1-carboxylate (C27, 15 mg).
