Versuchsvorschrift

A mixture of 66 mg (0.12 mmol) N-(4-Methoxy-phenyl)-N-(carboxypropyl-sulfonyl)-thieno[2,3-b]quinoline-4-carboxamide 17, 25 μl (0.17 mmol) 2-Morpholino-ethyl-isocyanide (MEI) and 21 mg (0.17 mmol) N-Hydroxysuccinimide (HOSu) was stirred overnight at room temperature. The solvent was removed under vacuum and the oily residue was purified by silica gel column chromatography (eluent: methylene chloride/acetone 9:1+0.1% acetic acid). The appropriate fractions were combined and evaporated to yield 75 mg of 18.
