Reaction Conditions

Reaction Steps

To a solution of ethyl (2E)-3-(6-{[(3R)-1-phenyl-3-pyrrolidinyl]amino}-3-pyridinyl)acrylate (47 mg) in dioxane (1.4 mL) was added 1N sodium hydroxide (0.42 mL). After stirring at 60° C. for 2 hours, the reaction mixture was added H2O (7 mL) and acidified with 1N hydrochloric acid (to pH 4). A resulting precipitate was collected by filtration, and washed with water to give (2E)-3-(6-{[(3R)-1-phenyl-3-pyrrolidinyl]amino}-3-pyridinyl)acrylic acid hydrochloride (39 mg).
