Procedure

To a stirred solution of [6-(2-Nitrobenzenesulfonylamino)-hexyl]-carbamic acid t-butyl ester (2.0 g, 4.9 mmol) in 25 mL of methylene chloride at room temperature was added 3 mL of saturated HCl solution in ethyl acetate and stirred for 4 h. The precipitated solid was filtered to yield the titled compound as white solid (1.58 g, 95%); mp 161-162° C.
