Reaction Steps

To a solution of ethyl 2-(5-acetamido-3-(4-fluorophenyl)-1H-pyrazol-1-yl)acetate (1.1 g, 3.7 mmol) in ethanol (33 mL) were added iodic acid (170 mg, 0.95 mmol) and iodine (480 mg, 1.9 mmol). The reaction was stirred for 90 min at 60° C. The reaction mixture was concentrated in vacuo and the residue was dissolved in CH2Cl2 and washed with a 2 N Na2SO3 solution. The organic phase was dried over MgSO4, filtered and evaporated to give ethyl 2-(5-acetamido-3-(4-fluorophenyl)-4-iodo-1H-pyrazol-1-yl)acetate as a white solid (1.63 g), which was used as such in the subsequent step.
