Hydrochloric Acid → 2-(Tert-butylsulfamoyl)acetic acid

참여 물질

반응 단계

To a solution of ethyl-2-(N-tert-butylsulfamoyl)acetate (4 g, 17.9 mmol.) in 65 mL of EtOH and 13 mL of H2O at 0° C. was slowly added NaOH (3.6 g, 89.5 mmol.). The reaction was allowed to room temperature and stirred overnight. TLC analysis showed the reaction complete. The mixture was acidified to pH=5 with aq. HCl (1M). The resulting mixture was extracted with EtOAc (30 mL×3). The combined organic layer was dried over Na2SO4, concentrated to afford crude 2-(N-tert-butylsulfamoyl)acetic acid (2.4 g, 69%), which was used directly without purification.
