Procedure

To a stirring solution of methyl [2-(N,N'-di-tert-butyloxycarbonylguanidino)ethyl]thioacetate (1.24 g, 3.17 mmol) in ethanol (15 mL) at room temperature (15 mL) was added 10% aqueous sodium hydroxide solution (3 mL). After 2 h, The mixture was concentrated, and the residue was treated with 10% aqueous HCl solution. The resulting mixture was extracted with ethyl acetate, and the organic extracts were washed with water and brine, dried over sodium sulfate, and concentrated to afford 1.06 g of [2-(N,N'-di-tert-butyloxycarbonylguanidino)ethyl]thioacetic acid as a white solid. 1H NMR (CDCl3) δ1.50 (s, 18), 2.89 (t, 2, J=8), 3.34 (s, 2), 3.72 (m, 2), 8.82 (br s, 2).
