Procedure

To a solution of (2E)-3-(5-chloro-6-{[1-(4-methylbenzyl)-4-piperidyl]amino}-3-pyridyl)-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (470 mg) in EtOH(2 ml) was treated with 2N HCl in EtOH (2.42 ml) and was stirred at 25° C. for 1 hour. The precipitate was collected, washed with EtOH, dried under reduced pressure to give (2E)-3-(5-chloro-6-{[1-(4-methylbenzyl)-4-piperidyl]amino}-3-pyridyl)-N-hydroxyacrylamide dihydrochloride (308 mg).
