Versuchsvorschrift
To a solution of Intermediate 1B (5.65 g, 24.75 mmol) in water (12 mL) was added acetic acid (49 mL, 0.86 mol). The resulting mixture was stirred under nitrogen for 6 hours. The reaction mixture was azeotroped with toluene and dried under vacuum to give the desired aldehyde, Intermediate 1C in quantitative yield as a white solid, which was used in the next step without further purification.
