Versuchsvorschrift

To ethyl 2-((3R)-1-(2-hydroxy-2-(3-(5-phenyl-4-(trifluoromethyl)isoxazol-3-yl)-4,5-dihydronaphtho[1,2-c]isoxazol-7-yl)ethyl)piperidin-3-yl)acetate (Preparation 19A, 125 mg, 0.210 mmol were added acetonitrile (3 mL) and 6N hydrochloric acid (3 mL). The reaction mixture was heated at 60° C. for 4 h. The reaction mixture was concentrated under reduced pressure to yield a solid. To the solid was added acetonitrile (0.5 mL) and water (10 mL). The contents were sonicated and lyophilized to yield 2-((3R)-1-(2-hydroxy-2-(3-(5-phenyl-4-(trifluoromethyl)isoxazol-3-yl)-4,5-dihydronaphtho[1,2-c]isoxazol-7-yl)ethyl)piperidin-3-yl)acetic acid, hydrochloric acid (150 mg, 0.248 mmol, 70.3% yield) as a white solid.
