Versuchsvorschrift

Methanesulfonic acid 4-oxo-5-[5-(7-trifluoromethyl-quinolin-4-yloxy)-pentyloxy]-4H-pyran-2-ylmethyl ester 16 (100 mg, 0.20 mmol) was dissolved in dichloromethane (5 mL). Morpholine (44 μL, 0.50 mmol) was added via syringe. The mixture was stirred at 45° C. for 18 h. After cooling to room temperature CH2Cl2 (75 ml) was added and the mixture was washed with NaHCO3 10% (3×50 mL) and brine (3×50 mL). The organic layer was dried over MgSO4, filtered and evaporated. The crude product was purified by column chromatography on silica using as eluent CH2Cl2:MeOH=9:1. 5-(5-(6-(Trifluoromethyl)quinolin-4-yloxy)pentyloxy)-2-(morpholinomethyl)-4H-pyran-4-one EHT 1426 was obtained (37 mg, 35% yield) as an orange oil.
