Procedure

(R)-3-{[1-(3,4-Difluoro-benzyl)-2-oxo-1,2-dihydro-pyridine-3-carbonyl]-amino}-3-[5-(1H-pyrrolo[2,3-b]pyridin-3-yl)-thiophen-2-yl]-propionic acid (0.026 g, 0.000049 mol;) was dissolved in N,N-Dimethylformamide (2 g, 0.03 mol;) and Ammonium chloride (0.0065 g, 0.00012 mol;), N,N-Diisopropylethylamine (42.4 uL, 0.000243 mol;), and N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium Hexafluorophosphate (0.024 g, 0.000063 mol;) were added. After 2 hours the reaction was found to be complete by LC-MS 1.17 534.06. The crude reaction was directly injected onto the Gilson for purification to give the pure product.
