Diisopropylethylamine → HCID 118071489, compound

Participants

Reaction Steps

To a mixture of 3-(2-aminoethyl)-5-methoxy-N-methyl-1H-indole-2-carboxamide hydrochloride (90.0 mg) and acetonitrile (5.00 mL) were added 2-fluoropropionic acid (0.0495 mL), diisopropylethylamine (0.272 mL), and 2-(7-aza-1H-benzotriazol-1-yl)-1,1,3,3-tetramethyluronium hexafluorophosphate (181 mg), followed by stirring at room temperature overnight. The reaction mixture was concentrated under reduced pressure and the obtained residue was purified by silica gel column chromatography (chloroform:methanol=10:0 to 10:1). The obtained residue was solidified with a mixed solvent of hexane:ethyl acetate=2:1 to obtain 3-{2-[(2-fluoropropanoyl)amino]ethyl}-5-methoxy-N-methyl-1H-indole-2-carboxamide (70.0 mg) as a white solid.
