Reaction Steps

To 4-(5-((5-chloro-2-oxoindolin-3-ylidene)methyl)furan-2-yl)-3-fluorobenzoic acid (40 mg, 0.104 mmol) in DMF was added HBTU (60 mg, 0.157 mmol) and DIEA (55 μL, 0.313 mmol). The mixture was stirred at room temperature then was added 1-methylhomopiperazine (16 μL, 0.125 mmol) and allowed to stir at room temperature. The solid formed was isolated by filtration and purified by HPLC to yield 5-chloro-3-((5-(2-fluoro-4-(4-methyl-1,4-diazepane-1-carbonyl)phenyl)furan-2-yl)methylene)indolin-2-one. LCMS (M+1=480).
