実験手順
Place 2-p-tolyl-5-trimethylsilanyl-2H-pyrazol-3-ylamine (170 mg, 0.693 mmol) in ethyl acetate (10 mL). Add potassium carbonate (191 mg, 1.38 mmol) and water (2 mL). Stir the reaction and add trichloroethyl chloroformate (0.114 mL, 0.831 mmol). Stir at room temperature for 18 hours. Add water and ethyl acetate. Separate organic layer and wash with saturated aq. sodium chloride. Collect organic layer, dry over Mg2SO4, filter, and concentrate under reduced pressure. Subject residue to silica gel chromatography eluting with 0-30% EtOAc:hexane to yield 280 mg (96%) of the title compound. MS(ES+): m/z=420.2 [M+H].
