Reaction Steps
A suspension of the faster eluting diastereomer of tert-butyl({1-[(2R)-2-hydroxy-2-(4-methyl-1-oxo-1,3-dihydro-2-benzofuran-5-yl)ethyl]pyrrolidin-2-yl}methyl)carbamate (710 mg, 1.82 mmol) in dioxane (2.0 mL) was treated with a solution of hydrochloric acid in dioxane (4.0 M, 2.0 mL). After shaking sixteen hours, the solvents were removed in vacuo to provide 5-[(1R)-2-[2-(aminomethyl)pyrrolidin-1-yl]-1-hydroxyethyl}-4-methyl-2-benzofuran-1(3H)-one hydrochloride which was carried on without purification.
