Reaction Steps

To solution containing (E)-tert-butyl 3-(3-(2-(3-hydroxybenzoyl)-1-isopropylhydrazinyl)-3-oxoprop-1-enyl)-1H-indole-1-carboxylate (100 mg, 0.22 mmol) and K2CO3 (35.8 mg, 0.26 mmol) dissolved in anhydrous acetonitrile (10.0 ml), iodomethane (0.0673 ml, 1.08 mmol) was added drop-by-drop at 0° C. The reaction mixture was refluxed for 12 hr at 85° C. After concentration under reduced pressure, the solution was separated through the silica gel chromatography (30% EtOAc) so that ivoty solid form of (E)-tert-butyl 3-(3-(1-isopropyl-2-(3-methoxybenzoyl)hydrazinyl)-3-oxoprop-1-enyl)-1H-indole-1-carboxylate was obtained (43.5 mg, 42.2%).
