反応手順
To a mixture of (S)-tert-butyl 1-(3-aminopyridin-4-yl)piperidin-3-ylcarbamate (1.04 g, 5.00 mmol) and 2-bromothiazole-4-carboxylic acid (1.46 g, 5.00 mmol) in Methylene chloride (10 mL, 200 mmol) was added N,N-Diisopropylethylamine (3.48 mL, 20.0 mmol) and N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium Hexafluorophosphate (2.28 g, 6.00 mmol). The reaction mixture was stirred at room temperature overnight. The reaction mixture was then concentrated and the residue was purified on silica eluting with 0 to 5% MeOH in DCM with 1% NH4OH (2.41 g, 99.9%). ESIMS m/z=484.1 (M+1).
