実験手順

Following general N—C coupling procedure 1, 5-bromo-2-nitropyridine (110 mg, 0.542), was combined with 2-Oxo-3,8-diaza-bicyclo[3.2.1]octane-8-carboxylic acid tert-butyl ester (135 mg, 0.596 mg), which after purification silica gel chromatography gave 3-(6-Nitro-pyridin-3-yl)-2-oxo-3,8-diaza-bicyclo[3.2.1]octane-8-carboxylic acid tert-butyl ester (290 mg, 81%). MS m/z 349.0 (MH+), and was used directly as is without further characterization.
