Reaction Steps

A mixture of 1-(6-amino-1-hexyl)-1,2-dihydroquinoline-2-one (320 mg), S-methyl-N-cyano-N′-4-pyridyl-isothiourea (210 mg), triethylamine (0.31 ml), 4-(N,N-dimethylamino)-pyridine (7 mg) and pyridine (10 ml) was stirred overnight at 60° C. After cooling to room temperature the pyridine was removed by evaporation twice with toluene in vacuo and the residue was distributed between water and ethyl acetate. The organic phase was dried and evaporated to yield a crude product which was purified by chromatography on silica gel with ethyl acetate/methanol/aqueous ammonia (40:10:1.25) as eluent. The pure fractions were pooled, evaporated, triturated with ethyl acetate and dried in vacuo to give the title compound.
