Procedure
To a solution of (2E)-3-(6-{[(3R)-1-benzyl-3-pyrrolidinyl]amino}-5-methyl-3-pyridyl)-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (306 mg) in MeOH (5.6 mL) was added hydrogen chloride methanol reagent 10 (1.4 mL, Tokyo Kasei), and the mixture was stirred at ambient temperature for 2 hours. To the reaction mixture was added Men and the solvent was removed in vacuo. Obtained colorless solid was triturated with Men to give (2E)-3-(6-{[(3R)-1-benzyl-3-pyrrolidinyl]amino}-5-methyl-3-pyridyl)-N-hydroxyacrylamide dihydrochloride (202.1 mg) as colorless powder.
