Versuchsvorschrift

A solution of N-((5-hydroxy-1-(2-methyl-4-phenylthiazole-5-carbonyl)piperidin-2-yl)methyl)quinoline-8-carboxamide (0.07 mmol, 0.036 g) in DCM (0.3 mL) was added to a mixture of bis(2-methoxyethyl)aminosulfur trifluoride (0.14 mmol, 0.027 mL) in DCM (0.2 mL) at −78° C. under argon. The resulting mixture was stirred at −78° C. for 1 h and at rt for another 1.5 h. The desired product was purified by preparative TLC to give N-((5-fluoro-1-(2-methyl-4-phenylthiazole-5-carbonyl)piperidin-2-yl)methyl)quinoline-8-carboxamide with unidentified stereochemistry (Y: 16%). MS (ESI) 489 (M+H).
