실험 절차

3-Nitro-6,7,8,9-tetrahydro-5-oxa-9-aza-benzocycloheptene (203 mg, 1.04 mmol) and 4-Dimethylaminopyridine (13 mg, 0.10 mmol) in Pyridine (3.5 mL) was treated with Methoxyacetyl chloride (0.15 mL, 1.6 mmol) was added to the vial and stirred at rt. After 4 h, the mixture was partitioned between EtOAc and water, separated and the org. layer was washed with 1N HCl. After washing with brine and drying, 2-Methoxy-1-(3-nitro-7,8-dihydro-6H-5-oxa-9-aza-benzocyclohepten-9-yl)-ethanone was isolated following silica gel chromatography (0-100% EtOAc:Hex) as yellow solids (270 mg, 97%). 1H-NMR (CDCl3): 7.96 (m, 2H), 7.36 (m, 1H), 4.82 (m, 1H), 4.25 (m, 2H), 3.89 (m, 3H), 3.34 (s, 3H), 2.96 (m, 1H), 2.13 (m, 2H).
