实验过程

3-Benzyloxycarbonylamino-1-(4-methoxy-benzenesulfonyl)-2,3,4,7-tetrahydro-1H-azepine-2-carboxylic acid tert-butyl ester (28 mg, 0.054 mmol) is dissolved in 4 ml Dichloro-methane/Trifluoroacetic Acid; 3:1 and stirred for 5 h at room temperature. The solvent/reagent are evaporated and the remaining oil is co-evaporated from Toluene twice. Flash-chromatography, Hexane/Ethylacetate; 1:1 afforded the desired product: Cal. 460.51, found (M)+ 460.9.
