Reaction Conditions

Reaction Steps

A solution of 4′-[(4-chloro-2-methyl-6-propylpyrimidin-5-yl)methyl]biphenyl-2-carbonitrile (0.72 g), pentane-1-sulfonamide (0.61 g) and potassium carbonate (0.55 g) in N,N-dimethylacetamide (10 mL) was stirred at 150° C. overnight. The reaction mixture was diluted with ethyl acetate, washed with 5% aqueous potassium hydrogen sulfate solution and then with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. A mixture of the residue, hydroxylammonium chloride (1.4 g), sodium hydrogen carbonate (2.0 g) and dimethyl sulfoxide (10 mL) was stirred at 90° C. overnight. The reaction mixture was diluted with ethyl acetate, washed with water and then with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The residue was dissolved in tetrahydrofuran (10 mL), N,N′-carbonyldiimidazole (0.49 g) and then 1,8-diazabicyclo[5.4.0]undec-7-ene (0.45 mL) were added, and the mixture was stirred at room temperature for 30 min. The reaction mixture was diluted with ethyl acetate, washed with saturated aqueous potassium hydrogen sulfate solution and then with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography to give the title compound (0.40 g, 38%) as a white solid.
