Procedure

2M ethanolic hydrogen chloride (2.0 mL) was added to the solution of (2Z)-3-(5-chloro-6-{[(3R)-1-(cyclohexylmethyl)-3-piperidinyl]amino}-3-pyridinyl)-2-fluoro-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (0.5 g) in EtOH (5 ml) and the mixture was stirred at ambient temperature for 3 hrs. To the reaction mixture was added AcOEt and isolated precipitate was collected by filtration to give (2Z)-3-(5-chloro-6-{[(3R)-1-(cyclohexylmethyl)-3-piperidinyl]amino}-3-pyridinyl)-2-fluoro-N-hydroxyacrylamide dihydrochloride (0.28 g),
