Benzyl Chloride → HCID 21497805, compound

Participants

Reaction Steps

The starting material is prepared as follows: To the mixture of 3.6 g of 4-(4-acetamidophenoxy)-3-amino-5-sulfamoylbenzoic acid, 10 ml of water andthe sufficient amount of N aqueous sodium hydroxide to reach a pH = 7.4, 1.3 g of benzyl chloride are added while stirring at 30°. The mixture is stirred for 16 hours at room temperature, during which time 4N aqueous sodium hydroxide is added dropwise to keep said pH value. It is filtered, the filtrate acidified with glacial acetic acid and the precipitate formed filtered off, to yield the 4-(4-acetamidophenoxy)-3-benzylamino-5-sulfamoylbenzoic acid which, on recrystallization from aqueous ethanol, melts at 255° with decomposition.
