Procedure

A solution of acetic acid (3.2 μL) in acetonitrile (29.2 μL) was added to the mixture of (2E)-N-hydroxy-3-(5-{[(3R)-1-(2-phenylethyl)-3-pyrrolidinyl]amino}-2-pyrazinyl)acrylamide (20 mg) in THF (0.1 mL) and acetonitrile (0.1 mL) and the mixture was stirred at ambient temperature for 5 minutes. To the mixture was added AcOEt (1.5 mL) and isolated precipitate was collected by filtration to give (2E)-N-hydroxy-3-(5-{[(3R)-1-(2-phenylethyl)-3-pyrrolidinyl]amino}-2-pyrazinyl)acrylamide acetate (18 mg).
