Versuchsvorschrift
Diisobutylaluminum hydride (1.0 M solution in THF, 5.5 mL, 5.50 mmol) was added dropwise to a 0° C. solution of the product from step A (500 mg, 1.84 mmol) in methylene chloride (15 mL). The resulting solution was stirred for 10 min at 0° C., quenched with methanol (0.25 mL) followed by 15% aq. Rochelle salt (20 mL), and allowed to stir at room temperature for 4 h. The layers were separated and the aqueous layer was extracted with methylene chloride (20 mL). The combined organic layers were dried (MgSO4) and concentrated to provide 415 mg (98%) of the title compound as a colorless solid. MS 231 (M+H)+.
