Sodium methanesulfinate → HCID 12807841, compound

Participants

Reaction Steps

3-Chloromethyl-1-methyl-4-quinolone hydrochloride (2.0 g.) was added portionwise during 1 minute to a stirred suspension of sodium methanesulphinate (5.0 g.) in anhydrous dimethylformamide (70 ml.) at room temperature. The mixture was stirred at this temperature for 16 hours, then evaporated to dryness. The residue was triturated with water (50 ml.), filtered, the filtrate basified with aqueous sodium hydroxide and then extracted with dichloromethane (2×50 ml.). The combined extracts were dried over anhydrous magnesium sulphate and evaporated to give the novel 1-methyl-3-methylsulphonylmethyl-4-quinolone, m.p. 201°-204° (from acetone).
