反応手順
To the solution of 2-amino-1-(4-bromo-phenyl)-ethanone (HCl salt, 1.0 g, 4 mmol) and 2-aza-bicyclo[2.2.1]heptane-2,3-dicarboxylic acid 2-tert-butyl ester (0.98 g, 4 mmol) in DMF (13 ml) was added HATU (1.64 g, 4.3 mmol), followed by slow addition of diisopropylethylamine (2.2 ml, 12.7 mmol). The mixture was stirred for 4 hours and was diluted with EtOAc. The organic phase was washed with 1 N NaOH solution, water, and brine, and was dried with sodium sulfate. Concentration and purification by flash column chromatography (hexane/EtOAc) gave 3-[2-(4-bromo-phenyl)-2-oxo-ethylcarbarnoyl]-2-aza-bicyclo[2.2.1]heptane-2-carboxylic acid tert-butyl ester (1.7 g). m/z: 460.9 (M+Na)+.
