Reaktionsschritte
To a solution of 3-iodoaniline (131 mg, 0.60 mmol) in 1.5 ml pyridine at room temperature was added over 2 minutes a solution of 1,3-dimethylpyrazole-5-carbonyl chloride (79 mg, 0.50 mmol) in 0.3 ml 1,2-dichloroethane. The reaction was stirred at room temperature for 30 minutes, quenched into a NaHCO3 solution, and extracted into EtOAc. The EtOAc solution was washed with NaHCO3 solution, brine, dried with anhydrous Na2SO4 and rotary evaporated. The resultant gummy solid was recrystallized from hexane/EtOAc to give the title compound as solid white needles (135 mg, 80%).
