Versuchsvorschrift

3.7 g of finely powdered lithium carbonate were added to a solution of 1.96 g of methyl (RS)-(2-tert-butoxycarbonylmethoxy-3,5-dichloro-phenyl)-[4-(N-hydroxycarbamimidoyl)-phenylamino]-acetate (see Example 276.2) in 200 ml of THF and 100 ml of water. The suspension was stirred for 8 hours at 55–60° C. The reaction mixture was then concentrated and the aqueous suspension remaining was neutralized with 100 ml 1N HCl. The precipitate was filtered off, washed with water and dried overnight at 50° C. in a high vacuum. There were obtained 1.59 g of (RS)-(2-tert-butoxycarbonylmethoxy-3,5-dichloro-phenyl)-[4-(N-hydroxycarbamimidoyl)-phenylamino]-acetic acid; MS (ISP) m/z 484.3 (M+H)+, 506.2 (M+Na)+.
