참여 물질

반응 단계

4.3 g (0.025 moles) of methyl-(N-3-hydroxyphenyl)-carbamate are reacted with 7.3 g (0.025 moles) of N-phenylcarbamoylbenzoic acid sulfimide (m.p.: 184°-186° C.) in 15 ml of acetone, in the presence of 2.56 g (0.025 moles) of triethyl amine, at 40° C. for 15 minutes. To the reaction mixture 40 ml of water are added and it is cooled to 5° to 10° C. The mixture is allowed to stand for 30 minutes, filtered, washed and dried. 5.5 g of 3-methoxycarbonylaminophenyl-phenyl carbamate are obtained, melting at 150° to 152° C.
