실험 절차

Chloroacetyl chloride (0.50 mL, 6.3 mmol; Acros) was added to a solution of 2-Nitro-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocycloheptene (0.58 g, 3.0 mmol;), Triethylamine (1.0 mL, 7.2 mmol), and 4-Dimethylaminopyridine (20 mg, 0.1 mmol; Acros) in Acetonitrile (10 mL) (Exothermic-immediate color change to a dark mixture). The reaction was stirred under an atmosphere of Nitrogen. After 1 h, Pyrrolidine (2.0 mL, 24 mmol) was added, as HPLC had shown the first acylation to be complete. After overnight stirring, the mixture was diluted with DCM (30 mL) and water (30 mL), the layers separated and the aq. extracted with 10 mL DCM. The combined organics were washed with brine (20 mL) and dried, then conc. The residue was chromatographed (ISCO, 40 g, 0-5% MeOH:DCM) to afford 1-(2-Nitro-7,8-dihydro-6H-5-oxa-9-aza-benzocyclohepten-9-yl)-2-pyrrolidin-1-yl-ethanone as a yellow oil (807 mg, 88%). 1H-NMR (CDCl3): rotamers, broad spectrum; 13C-NMR (CDCl3): 169.8, 160.3, 142.5, 133.6, 124.8, 124.2, 122.1, 70.9, 57.6, 54.0, 45.3, 28.0, 23.7
