Procedure
3-[(4-Chloro-benzyl)-methoxycarbonylmethyl-amino]-pyrrolidine-1-carboxylic acid tert-butyl ester (3.5 g, 9.1 mmol) was dissolved in 4N HCl in dioxane (60 mL). The resultant solution was stirred for 2 h at rt then concentrated to provide the desired product as a white solid. LCMS (retention time=1.26, ES+283)
