Versuchsvorschrift

A mixture of 17.17 gm of ethyl N-[3-(2-bromoacetyl)-phenyl]-carbamate, 7.1 gm of amidinothiourea and 45 ml of ethanol was refluxed for 4 hours and then cooled to room temperature. The precipitate formed thereby was filtered off and washed with cold ethanol, yielding 22 gm of the title compound, m.p. 240°-2° C.
