Procedure

To a solution of tert-butyl [(3R)-1-(3-fluorobenzyl)-3-pyrrolidinyl](5-{(1E)-3-oxo-3-[(tetrahydro-2H-pyran-2-yloxy)amino]-1-propen-1-yl}-2-pyridyl)carbamate [(251 g) in MeOH (37 mL) was added hydrogen chloride methanol reagent 10 (9.28 mL, Tokyo Kasei), and the mixture was stirred at ambient temperature for 1 hour. The solvent was removed in vacuo and the residue was dissolved in dioxane (12 mL). To the reaction mixture was added 4N HCl in dioxane and stirred for 1 hour at ambient temperature. To the reaction mixture was added CH3CN and the solvent was removed in vacuo. Obtained colorless solid was triturated with CH3CN to give (2E)-3-(6-{[(3R)-1-(3-fluorobenzyl)-3-pyrrolidinyl]amino}-3-pyridyl)-N-hydroxyacrylamide dihydrochloride (1.87 g) as colorless powder.
