Hydrochloric Acid → (E)-3-[6-[N-(carboxymethyl)amino]pyridin-3-yl]-N-methyl-N-(2-methyl-1H-indol-3-ylmethyl)acrylamide

Participants

Reaction Steps

To a stirred solution of (E)-3-[6-[N-(methoxycarbonylmethyl)amino]pyridin-3-yl]-N-methyl-N-(2-methyl-1H-indol-3-ylmethyl)acrylamide (0.5 g, 1.3 mmole) in dioxane (30 mL) was added 1 N NaOH (2 mL, 2 mmole). After stirring for 18 h the reaction was neutralized with 1 N HCl (2 mL, 2 mmole) and concentrated to near dryness. The resulting suspension was diluted with H2O and filtered. The solid was washed with H2O and dried under vacuum to give the title compound (505 mg, 100%) as a off-white solid: MS (ES) m/e 379.2 (M+H)+.
