N-(3-iodo-1-((2-methylthiazol-5-yl)methyl)-1H-indazol-4-yl)-7-(2-(4-methylpiperazin-1-yl)ethoxy)imidazo[1,2-a]pyridine-3-carboxamide → 7-(2-(4-methylpiperazin-1-yl)ethoxy)-N-(1-((2-methylthiazol-5-yl)methyl)-1H-indazol-4-yl)imidazo[1,2-a]pyridine-3-carboxamide

Reaction Steps

A solution of N-(3-iodo-1-((2-methylthiazol-5-yl)methyl)-1H-indazol-4-yl)-7-(2-(4-methylpiperazin-1-yl)ethoxy)imidazo[1,2-a]pyridine-3-carboxamide (11.5 mg, 0.018 mmol) in absolute EtOH (1 mL) was treated with Pd/C (Degussa, wet, 10% wt, 2 mg), the reaction flask was flushed with hydrogen, and stirring at ambient temperature was continued for seven hours. The reaction was diluted with DCM, the catalyst was removed by filtration, and the filtrate concentrated to afford the crude product. The crude product was subjected to preparative thin-layer chromatography on silica with ammonia/MeOH/DCM as eluent to afford 1.9 mg of the desired product. MS (ES+APCI) m/z=531 (M+H) detected.
