Procedure

Into a round bottom was added 1-(3,4-Difluoro-benzyl)-2-oxo-1,2-dihydro-pyridine-3-carboxylic acid (0.400 g, 0.00151 mol;), N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium Hexafluorophosphate (0.573 g, 0.00151 mol;), Methylene chloride (14 mL, 0.23 mol;), and N,N-Diisopropylethylamine (1310 uL, 0.00754 mol;). The reaction was stirred until all contents were dissolved and preactivation was complete. (R)-3-Amino-3-thiophen-2-yl-propionic acid (0.28 g, 0.0016 mol;) was added and the reaction was allowed to stir for 1-2 hours then an LC-MS was taken which showed product at 1.47. The reaction was worked up by washing with citric acid and brine then drying with magnesium sulfate. The crude concentrated reaction was taken on directly to the next step. ES (+) MS m/e=419.08
