(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 mL, 0.03 mol;) and 2.0 M of Dimethylamine in Tetrahydrofuran (0.243 mL) then N,N,N′,N′-Tetramethyl-O-(7-azabenzotriazol-1-yl)uronium Hexafluorophosphate (0.024 g, 0.000063 mol;) was added. The reaction was allowed to stir for 2 hours and LC-MS showed disappearance of starting material and appearance of product at 1.28 562.10. The reaction was purified by Gilson Preparative HPLC and the pure fractions were concentrated.
