Versuchsvorschrift
(5-Chloro-2,6-dinitro-phenyl)-phenyl-methanol (13) (0.5 g, 1.90 mmol) or (5-chloro-2,4-dinitro-phenyl)-phenyl-methanol (14) (0.5 g, 2.67 mmol) were treated with 2M solution of dimethylamine in methanol (6 mL) and the solution was heated in a microwave reactor (CEM Focused Microwave™ Synthesis System Model Discover) at 50-55° C. for 15 minutes. The solvent was removed in vacuo and each residue was coevaporated with dichloromethane (2×10 mL) and applied onto a column of silicagel. The column was eluted with dichloromethane/ethanol (49:1) to give compounds 17 and 18.
