Participants

Reaction Steps

tert-Butyl({5-[(4-fluorophenyl)sulfonyl]-1-(2-fluoropyridin-3-yl)-1H-pyrazol-3-yl}methyl)methylcarbamate (132 mg) was dissolved in ethyl acetate (2 ml) and 2-propanol (1 mL), and 4 mol/L hydrogen chloride-ethyl acetate solution (3 mL) was added. After stirring at room temperature for 2 hr, the reaction mixture was concentrated under reduced pressure, and the residue was recrystallized from a mixed solvent of ethanol and ethyl acetate to give the title compound as colorless crystals (yield 83 mg, yield 73%). melting point 211-214° C.
