Versuchsvorschrift
A solution of 1-[2-(tert-butyldimethylsilanyloxy)ethyl]-5-fluoro-3,4-dihydro-1H-quinoxalin-2-one from Example 21E (110 mg, 0.34 mmol) and diisopropylethylamine (77 μl, 0.44 mmol) in THF (8.0 ml) and a solution of phosgene in toluene (20%, 233 μl, 0.44 mmol) were stirred together for 2 h. A solution of 4-aminomethyl-N-(2-furan-2-ylphenyl)-3,N-dimethylbenzamide from Example 21D (108 mg, 0.34 mmol) and diisopropylethylamine (77 μl, 0.44 mmol) in THF (5.0 ml) was added and the mixture was stirred for 18 h and evaporated in vacuo. The residue was directly in the next step of the synthesis as described in Example 21G.
