実験手順
1-(3,4-Difluoro-benzyl)-2-oxo-1,2-dihydro-pyridine-3-carboxylic acid (0.23 g, 0.00088 mol;) was dissolved in N,N-Dimethylformamide (9 mL, 0.1 mol;) and N,N-Diisopropylethylamine (800 uL, 0.004 mol;), and N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium Hexafluorophosphate (0.37 g, 0.00097 mol;) were added. After 5 minutes preactivation Amino-thiophen-2-yl-acetic acid (0.266 g, 0.00169 mol;) was added. Workup consisted of rinsing with 5% citric acid then brine after dissolving the crude in ethyl acetate. The organic layer was then dried with magnesium sulfate and concentrated. The crude material was brought on directly to the next step. ES (+) MS m/e=404.81
