실험 절차

This example describes the preparation of an azidoaryl-substituted cyclooctene by reaction of an acid chloride-substituted phenyl azide with 5-aminocyclooctene. The reactions are illustrated in Scheme 4. 4-Azidobenzoic acid was converted to the corresponding acid chloride (10) with thionyl chloride and triethylamine in dry tetrahydrofuran. An excess of 5-aminocyclooctene was then introduced to the solution of the acid chloride at 0° C. to form the azidoaryl-substituted cyclooctene, 4-azido-N-4-cycloocten-1-yl-benzamide (9), which was purified by recrystallization from diethyl ether/hexane in 73% yield. The product was characterized by proton and carbon-13 nuclear magnetic resonance spectroscopy (1H and 13C NMR), as well as Fourier Transform Infrared (FTIR) spectroscopy. Key features in the characterization of 4-azido-N-4-cycloocten-1-yl-benzamide included the presence of the amide carbonyl in the 13C NMR spectrum at 165.1 parts per million (ppm), and a characteristic azide signal in the IR spectrum at 2120 reciprocal centimeters (cm−1).
