4-Methyl-6-[4-(2-pyridyl-mercapto)-butoxy]-carbostyril → 4-Methyl-6-[4-(2-pyridyl-sulfinyl)-butoxy]-carbostyril

Participants

Reaction Steps

A solution of 0.170 gm (0.0005 mol) of 4-methyl-6-[4-(2-pyridyl-mercapto)-butoxy]-carbostyril in 5 ml of glacial acetic acid and a solution of 0.107 gm (0.0005 mol) of sodium metaperiodate in 6 ml of water were admixed and allowed to stand at room temperature for 22 hours. Subsequently, the light brown reaction solution was diluted with 20 ml of water, and the reaction product was extracted with chloroform. The extract was shaken once with an aqeuous sodium carbonate solution and dried over anhydrous magnesium sulfate. After evaporating the organic phase, the residue was recrystallized from toluene.
