실험 절차

To a solution of tert-butyl [(3R)-1-(cyclopentylmethyl)-3-pyrrolidinyl](5-{(1E)-3-oxo-3-[(tetrahydro-2H-pyran-2-yloxy)amino]-1-propen-1-yl}-2-pyridinyl)carbamate (179 mg, 0.35 mmol) in MeOH (1 mL) was added hydrogen chloride methanol reagent 10 (3 mL, Tokyo Kasei), and the mixture was stirred at ambient temperature for 1 hr. The solvent was removed in vacuo and the residue was dissolved in dioxane (1 mL). To the reaction mixture was added 4N HCl in dioxane (4 mL) and stirred for 1 hr at ambient temperature. To the reaction mixture was added MeCN and the solvent was removed in vacuo. Obtained colorless solid was triturated with MeCN to give (2E)-3-(6-{[(3R)-1-(cyclopentylmethyl)-3-pyrrolidinyl]amino}-3-pyridinyl)-N-hydroxyacrylamide dihydrochloride (115 mg, 85%) as colorless powder.
