To a solution of trans-3-[4-(4-Chloro-phenyl)-[1,4]diazepan-1-yl]-4-hydroxy-pyrrolidine-1-carboxylic acid tert-butyl ester (0.820 g, 2.08 mmol) in methylene chloride (1 mL) was added 4 N HCl/dioxane (10 mL, 40 mmol). The solution was stirred at rt for 1 hour, upon which a brown precipitate formed. The reaction was concentrated in vacuo to yield 0.930 g (˜100%) of the title compound. ESI-MS m/z: 296 (M+1), FAS method rt: 0.83 min.
