1-(3,4-Difluoro-benzyl)-2-oxo-1,2-dihydro-pyridine-3-carboxylic acid [4-(1-benzenesulfonyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-thiophen-2-ylmethyl]-amide (0.050 g, 0.000081 mol;) was dissolved in Methylene chloride (3 mL, 0.05 mol;) then 0.5 M of Sodium methoxide in methanol (3 mL) was added and the reaction was heated at 75 C for 1 hour. LC-MS showed the disappearance of starting material and the appearance of product at 1.34 477.10. The reaction was concentrated and dissolved in DMSO and methanol 1:1 for purification by Gilson Preparative HPLC. Pure fractions were combined and concentrated. ES (+) MS m/e=477.10; NMR (400 MHz, DMSO-d6) δ ppm 4.72 (m, 2H), 5.21 (s, 2H), 6.60 (t, 1H, J=8 Hz), 7.19 (m, 2H), 7.37-7.50 (m, 3H), 7.62 (s, 1H), 7.86 (m, 1H), 7.64 (s, 1H), 8.24 (m, 1H), 8.41 (m, 1H), 10.04 (t, 1H, J=6 Hz).
