Sodium Hydroxide → 4-{[(Methylsulfonyl)amino]methyl}benzoic acid

Participants

Reaction Steps

To a solution of 4-(aminomethyl)benzoic acid (4 g, 26.5 mmol) and NaOH 1M (52.9 ml, 52.9 mmol) in THF (60 ml), methanesulfonyl chloride (2.474 ml, 31.8 mmol) was slowly added and the reaction was stirred at RT overnight. The mixture was acidified and extracted twice with EtOAc; the combined organic layers were washed with brine, dried over Na2SO4 and evaporated to dryness. The resulting solid was suspended in MeOH (120 ml) and stirred overnight. The precipitate was collected by filtration to give 4-(methylsulfonamidomethyl)-benzoic acid (1.99 g, 8.68 mmol, 32.8% yield, MS/ESI+ 229.9 [MH]+).
