Reaction Steps

To a solution of 1-Amino-2-(isopropylsulphonyl)benzene (0.955 g, 4.80 mmol) in 2 mL of DMF at 0° C. was added NaH (60% in oil, 0.349 g, 8.72 mmol) in one portion. After stirring for 20 min, 2,4,5-trichloropyrimidine was added. The mixture was stirred at 0° C. for 30 minutes, and then at room temperature for 2 h. After quenching with saturated ammonium chloride solution, the mixture was poured in water and ethyl acetate mixture. Yellow suspension was filtered as final product (0.3 g, 20% yield). MS/ES+: m/z=346.
