Procedure
0.43 g of 3-{1-[3-(4-tert-butoxycarbonylaminomethylphenyl)-2-oxo-5-oxazolidinylcarbonyl]-4-piperazinyl}propionic acid, acetate, is stirred in 30 ml of ethereal HCl solution at room temperature. The precipitate formed is filtered off with suction, washed with a little ether and dried. 3-{1-[3-(4-aminomethylphenyl)-2-oxo-5-oxazolidinylcarbonyl]-4-piperazinyl}propionic acid, dihydrochloride, is obtained, m.p. 184°-186°.
