Potassium phenoxide reacted with 4-substituted 3’-methylsulfanyl-3,4’-diquinolinyl sulfides (1 or 3) at the substituent at the C4 position. 3’-Methylsulfinyl group promotes nucleophilic substitution of 4’-quinolinyl sulfur bond in sulfoxides (2) and (4) in which case, after treatment with potassium phenoxide, it led to 4-phenoxy-3-methylsulfinylquinoline (9) and 4-substituted 3-quinolinethiolates (5A, 6A or 7A), trapped by methylation to form 4-substituted 3-methylsulfanylquinolines (5a), (6a) and (7a) or their 5-, 6- and 8-nitro derivatives (5b,c), (6b,d) and (7b,d), respectively. Synthesis of 5-, 6- and 8-nitro-3-methylsulfanyl-4(1H)-quinolinones (10b,c,d) was described.
