Hydrochloride methanol → (2E)-3-{6-[(1-benzyl-3-pyrrolidinyl)amino]-3-pyridyl}-N-hydroxyacrylamide dihydrochloride

Participants

Reaction Steps

A solution of 10% HCl-MeOH solution (0.75 ml) was added to a mixture of (2E)-3-{6-[(1-benzyl-3-pyrrolidinyl)amino]-3-pyridyl}-N-(tetrahydro-2H-pyran-2-yloxy)acrylamide (170 mg) in MeOH 3 ml) and stirred at 15-25% for 2 hours. The reaction mixture was evaporated in vacuo and the residue was triturated with small amount MeOH and acetone and the precipitate was collected by filtration to give (2E)-3-{6-[(1-benzyl-3-pyrrolidinyl)amino]-3-pyridyl}-N-hydroxyacrylamide dihydrochloride (107 mg)
