Reaction Steps

To a stirred solution of (2E)-3-(5-{[(3R)-1-benzyl-3-pyrrolidinyl]amino}-2-pyrazinyl)-N-hydroxyacrylamide (300 mg) in 95% ethanol (3 mL) was added 4-methylbenzenesulfonic acid hydrate (168 mg) at ambient temperature. After stirring at the same temperature for one hour, additional 95% ethanol(1.5 mL) was added to the mixture. The precipitate was collected after two hours to afford (2E)-3-(5-{[(3R)-1-benzyl-3-pyrrolidinyl]amino}-2-pyrazinyl)-N-hydroxyacrylamide 4-methylbenzenesulfonate (253 mg) as a pale brown solid.
