Procedure

To a solution of (2E)-3-(5-{[(3R)-1-(4-chlorobenzyl)-3-pyrrolidinyl]amino}-2-pyrazinyl)-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (1.43 g) in methanol (16 mL) was added hydrogen chloride in methanol (6.24 mL). After stirring at room temperature for 1 hour, the reaction mixture was evaporated in vacuo and triturated with ethyl acetate to give (2E)-3-(5-{[(3R)-1-(4-chlorobenzyl)-3-pyrrolidinyl]amino}-2-pyrazinyl)-N-hydroxyacrylamide dihydrochloride (1.40 g).
