Versuchsvorschrift
A mixture of (R)-2-(3-{[2-(3,5-difluoro-phenoxy)-ethyl]-methyl-amino}-propylamino}-1-(6-methoxy-quinolin-4-yl)-ethanol (105 mg, 0.24 mmol), DMAP-(38 mg, 0.31 mmol), 1,1′-carbonyldiimidazole (51 mg, 0.31 mmol) and methylene chloride stabilised on amylene (4 ml) was stirred at room temperature for 16 hours. The solvent was concentrated and the residue was chromatographed on silicagel eluting with methylene chloride-methanol (94-6) to give (R)-3-(3-{[2-(3,5-difluoro-phenoxy)-ethyl]-methyl-amino)-propyl)-5-(6-methoxy-quinolin-4-yl)-oxazolidin-2-one (70 mg, 62%).
