Sodium Bicarbonate → 2-(4-((sulfamoylamino)methyl)phenyl)-N-((2-m-tolyl-6-(trifluoromethyl)pyridin-3-yl)methyl)propanamide

Participants

Reaction Steps

To a solution of tert-butyl N-(4-(1-oxo-1-((2-m-tolyl-6-(trifluoromethyl)pyridin-3-yl)methylamino)propan-2-yl)benzyl)sulfamoylcarbamate (250 mg, 0.412 mmol) in dichloromethane (2 mL) trifluoroacetic acid (0.2 mL) was added at room temperature. The mixture was stirred 12 h at room temperature. The mixture was neutralized by sodium bicarbonate to pH 7-8 and extracted with ethyl acetate and washed with brine. Drying over magnesium sulfate, evaporation of the ethyl acetate and purification by column chromatography gave 2-(4-((sulfamoylamino)methyl)phenyl)-N-((2-m-tolyl-6-(trifluoromethyl)pyridin-3-yl)methyl)propanamide (example 88) (138 mg, 66%).
