Sodium Hydroxide → 4-[(Methylsulfonyl)amino]benzoic acid sodium salt

Participants

Reaction Steps

To 500 ml of water is added 63.4 g (1.59 mole) of sodium hydroxide and the mixture is stirred until all the solid has dissolved. To this is slowly added 310 g (1.44 mole) of 4-[(methylsulfonyl)amino]benzoic acid. The reaction is stirred for 15 minutes at ambient temperature after all the solid has dissolved. After removal of the water in vacuo, the residue is triturated with isopropyl alcohol, evaporated, triturated with acetone and concentrated in vacuo. The solid is dried under vacuum for 72 hours to provide 333.7 g of the title compound.
