Versuchsvorschrift

A mixture of 2-oxa-5-azaspiro[3.4]octane (0.1 mmol, 15.8 mg), 1-{(4S,5R)-5-[4-(6-Chloromethyl-pyridin-3-yl)-phenyl]-4-fluoromethyl-2,2-dimethyl-oxazolidin-3-yl}-2,2-difluoro-ethanone (Example 99, Step 2, 0.09 mmol, 37 mg) and cesium carbonate (0.25 mmol, 81 mg) and acetonitrile (1 mL) was heated to 55° C. for 5 hours. The crude mixture was filtered on a bed of celite and the cake was washed with CH2Cl2 (2 mL). The volatiles were removed. The crude mixtures were used “as is” in step 2.
