Reaction Steps

The mixture of ethyl (2E)-3-(5-{[(3R)-1-(3-chlorobenzyl)-3-piperidinyl]amino}-2-pyrazinyl)acrylate (235 mg, 0.59 mmol) and 1N-NaOH (1.2 mL) in EtOH (2 mL) was stirred at ambient temperature for 1 hr and the mixture was allowed to stand for 18 hrs. The reaction mixture was adjusted to PH 5.0 with 1 mol/L hydrochloric acid and evaporated in vacuo to give (2E)-3-(5-{[(3R)-1-(3-chlorobenzyl)-3-piperidinyl]amino}-2-pyrazinyl)acrylic acid (218 mg, 100%).
