Versuchsvorschrift

Potassium carbonate (1208 mg, 8.74 mmol) was added to a mixture of 1-(5-((tert-butyldiphenylsilyloxy)methyl)-4-((2R,6S)-2,6-dimethylmorpholino)-2,3-difluorophenyl)-2-chloroethanone (Intermediate 127, 500 mg, 0.87 mmol) and 1H-1,2,4-triazole (66.4 mg, 0.96 mmol) dissolved in 15 ml of Acetonitrile. The mixture was stirred at room temperature for 3 hours. Potassium carbonate was filtered from the mixture, and the filtrate was diluted with water and extracted with ethyl acetate (2×100 mL). The organic phases were combined, dried (Na2SO4), and concentrated. The crude residue (482 mg, 91%) contained mainly desired title compound and was used in the next step without further purification.
