Reaction Steps

Under argon atmosphere, 96 mg of 60% sodium hydride was suspended in 6 ml of N,N-dimethylformamide, and 388 mg of 4-iodo-1H-pyrazol was added at 0° C., and the mixture was stirred at 0° C. for 30 minutes. Subsequently, 0.21 ml of 2-bromopropane was added and the reaction mixture was stirred at 100° C. for 2 hours. The reaction solution was added with water. The solution was subjected to extraction with ethyl acetate. The organic layer was washed with brine and then dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and then the obtained residue was purified by silica gel column chromatography to obtain 328 mg of the objective compound.
