Versuchsvorschrift

To a solution of 2-benzylamino-3,4,5,6-tetrahydrobenzamide 21a (15 g) in glacial acetic acid (100 mL) was added excess hydrogen sulfide at 80° C. for 4 h. The reaction mixture was evaporated and ether was added to the residue which afforded crystallisation. The crystals were dissolved in ethyl acetate (30 mL) and a solution of bromine (8.3 mL) in ethyl acetate (30 mL) was dropwise added at room temperature. The mixture was stirred for 20 h at room temperature and evaporated. Column chromatography on silica gel (eluent: ethyl acetate-ethanol 1:1 containing 1% glacial acetic acid) gave the title compound (3.3 g): mp 157-158° C.
