Reaction Steps

A mixture of (2E)-3-(5-{[(3R)-1-(2-fluorobenzyl)-3-pyrrolidinyl]amino}-2-pyrazinyl)-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (600 mg) and 2N HCl/Ethanol (13.6 ml, 20 eq) was stirred at room temperature for 2 hours. After then, ethyl acetate (10 ml) and IPE (50 ml) was added and stirred. Precipitate was filtered, washed with IPE, and dried under reduced pressure to give 486 mg (83%) of (2E)-3-(5-{[(3R)-1-(2-fluorobenzyl)-3-pyrrolidinyl]amino}-2-pyrazinyl)-N-hydroxyacrylamide dihydrochloride as a powder.
