実験手順

To a solution of 9b-morpholino-3-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-4,9b-dihydro-3aH-chromeno[3,4-d]isoxazole-7-carbaldehyde (Preparation 60F, 0.070 g, 0.140 mmol) in methanol (1.0 mL) at room temperature was added sodium borohydride (1.43 mg, 0.038 mmol). The reaction mixture was stirred at room temperature for 30 min. Methanol was removed under reduce pressure, and the residue was diluted with dichloromethane, washed with water, and dried over anhydrous sodium sulfate. Concentration under reduced pressure afforded (9b-morpholino-3-(3-phenyl-4-(trifluoromethyl)isoxazol-5-yl)-4,9b-dihydro-3aH-chromeno[3,4-d]isoxazol-7-yl)methanol as a yellow oil. The product had an HPLC ret. time=2.83 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=502.0.
