Reaction Steps

To 2-(4-Fluoro-phenyl)-6-(methanesulfonyl-methyl-amino)-5-vinyl-furo[2,3-b]pyridine-3-carboxylic acid methylamide (11 mg, 0.027 mmol) was added 8 mg of 20% Pd(OH)2/C and ethyl acetate/methanol 5/1 (5 ml). The reaction flask was evacuated and filled with hydrogen gas from a balloon. After LCMS indicated conversion to product, the reaction mixture was filtered, evaporated to dryness and purified by HPLC to afford 5-Ethyl-2-(4-fluoro-phenyl)-6-(methanesulfonyl-methyl-amino)-furo[2,3-b]pyridine-3-carboxylic acid methylamide. MS (ESI) m/z 406.3 (M+1). 1H NMR (400 MHz, CDCl3) δ ppm 8.18 (s, 1H), 7.96-7.92 (m, 2H), 7.25-7.20 (m, 2H), 5.79 (br s, 1H), 3.32 (s, 3H), 3.19 (s, 3H), 2.99-2.98 (d, 3H), 2.96-2.91 (q, 2H), 1.33-1.29 (t, 3H).
