Traitement

  1. 1
    AutreThe reaction mixture was purified by flash chromatography over silica gel eluting with MeOH/DCM

Mode opératoire

A solution of 6-((2-tert-butoxy-2-oxoethyl)(pyridin-2-ylmethyl)amino)hexanoic acid (0.6545 g, 1.95 mmol), sulfanilamide (0.362 g, 2.10 mmol) and HATU (0.798 g, 2.10 mmol) in DMF (10 mL) and Et3N (1.0 mL) was stirred at 40° C. overnight. The reaction mixture was purified by flash chromatography over silica gel eluting with MeOH/DCM to give tert-butyl 2-((6-oxo-6-(4-sulfamoylphenylamino)hexyl)(pyridin-2-ylmethyl)amino)acetate (297 mg, 31%). ESMS m/z: 491.3 (M+H)+.
