Versuchsvorschrift
A solution of 110 mg (0.25 mmol) 2-{4-[5-(4-chloro-phenyl)-pyridin-2-ylethynyl]-2-methyl-phenoxy}-ethyl methanesulphonate in 2.11 mL (25 mmol) pyrrolidine is heated to 70° C. for 3 h. The mixture is evaporated down i.vac., the residue is combined with water, extracted exhaustively with DCM and the organic phase is dried over Na2SO4. After the desiccant and solvent have been eliminated and after recrystallisation from EtOH the desired product is obtained.
