Versuchsvorschrift

A mixture of 7-(2,2-dimethyl-1,3-dioxolan-4-yl)-9b-morpholino-3-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-4,9b-dihydro-3aH-chromeno[3,4-d]isoxazole (Preparation 60D, 0.080 g, 0.140 mmol) and TFA (3.00 ml, 38.9 mmol) was stirred at room temperature for 60 min. The TFA was removed under reduced pressure, and the residue was diluted with dichloromethane, washed with a saturated aqueous solution of sodium bicarbonate, and dried over anhydrous sodium sulfate. Concentration under reduced pressure afforded a quantitative yield of 1-(9b-morpholino-3-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-4,9b-dihydro-3aH-chromeno[3,4-d]isoxazol-7-yl)ethane-1,2-diol as a yellow oil. The product had an HPLC ret. time=2.63 min.−Column: Chromolith SpeedROD 4.6×50 mm (4 min.); Solvent A=10% MeOH, 90% H2O, 0.1% TFA; Solvent B=90% MeOH, 10% H2O, 0.1% TFA. LC/MS M+1=532.0.
