YieldReaction ConditionsOperation in experiment
82% With triethylamine; In N,N-dimethyl-formamide; at 50℃; for 24h; [0250] A solution of <strong>[133446-99-8]methyl 2-(bromomethyl)-4-nitro-benzoate</strong> (1.00 g, 3.65 mmol), (S)-3-aminoazepan-2-one (0.468 g, 3.65 mmol) and triethyl amine (1 mL, 7 mmol) in dimethyl formamide (10 mL) was stirred for 1 day at 50 C. The solution was then cooled to room temperature, water (50 mL) was added, and the mixture cooled in an ice water bath for 10 minutes. The resulting precipitate was filtered and dried to afford the title compound as an off-white solid (0.864 g, 82% yield).

YieldReaction ConditionsOperation in experiment
44.2% With triethylamine; In N,N-dimethyl-formamide; at 20 - 85℃; for 16h; [0511] To a solution of <strong>[165111-46-6]methyl 2-(bromomethyl)-4-cyanobenzoate</strong> (4.28 g, 16.85 mmol) in DMF (80 mL) at rt was added (S)-3-aminoazepan-2-one (2.59 g, 20.22 mmol), followed by TEA (3.40 g, 33.7 mmol). The suspension was stirred at 85C for 16 hrs, the solvent was removed and the residue was diluted with water (20 mL). The suspension was stirred at rt for 30 min, filtered, and the filter cake was washed with water, dried in vacuum providing (S)-1-oxo-2-(2-oxoazepan-3-yl)isoindoline-5-carbonitrile (2.30 g, 44.2% yield) as a light yellow solid. MS (ESI) m/z 270.1 [M+H] +.
