Syntheses of some Bunte's salts, isothiourea derivatives and thioethers, potential radioprotective agents. Part 40

By reacting respective halogen-derivatives with sodium or potassium thiosulphate there were obtained sodium or potassium salts of S-thiosulphates of 1-ureidocarbonyl-1-butyl, 3,4-dihydroxyphenacyl, carbophenoxymethyl, 2-hydroxyphenacyl, /N-(4-iodophenyl) carbamyl/methyl, /N-(4-iodophenyl) carbamyl/ethyl, /N-(2-iodophenyl) carbamyl/-methyl, /N-(2-iodophenyl) carbamyl/ethyl, /N-(6-carbomethoxybenzothiazolyl-2)-carbamyl/methyl, (2,4-dihydroxy-6-methylpyrimidyl-5)-methyl and (2,4-dihydroxypyrimidyl-5)-methyl. Reactions of thiourea with respective halogen-derivatives yielded hydrochlorides of 1-methyl-02-amidinothiomethylbenzimidazole, 1-ethyl-2-amidinothiomethylbenzimidazole, S-/N-(2-iodophenyl) carbamylethyl/ isothiourea, 5-amidinothiomethyl-6-methyl-2,4-dihydroxypyrimide and 5-amidinothiomethyl-2,4-dihydroxypyrimidine. Reactions of 4-chloroquinoline N-oxide with respective mercaptanes afforded thioether derivatives of quinoline N-oxide: 4-(p-chlorophenylthio)-4-(t-butylthio)-, 4-(3-naphtylthio)-, 4-(3-naphtylaminoacetylthio), 4-(benzimidazolythio)-, 4-(benzothiazolylthio) - and 4-benzoxalylthio.
