One gram of trans-(±)-1-n-propyl-6-oxo-7-dimethylaminomethylenedecahydroquinoline was reacted with 0.33 g. of thiourea in 20 ml. of ethanol by refluxing overnight under a nitrogen atmosphere. The volatile constituents were removed in vacuo to yield trans-(±)-2-mercapto-6-n-propyl-5,5a,6,7,8,9,9a,10-octahydropyrimido[4,5-g]quinoline free base. The free base was converted to the dihydrochloride salt by standard procedures to yield 0.17 g. of dihydrochloride salt melting at 267°-277° C. after recrystallization from methanol.
