Procedure

To a suspension of sodium hydride (60% dispensed in mineral oil, 0.97 g, 24 mmol) in anhydrous tetrahydrofuran (80 mL), was added 4-aminobenzenethiol (2.77 g, 22 mmol) dissolved in tetrahydrofuran (20 mL) over 5 minutes. The mixture was stirred at room temperature for 30 minutes, to this was added a solution of 2,4-dichloropyrimidine (3.00 g, 20 mmol) dissolved in tetrahydrofuran (20 mL) over 5 minutes. The resulting mixture was stirred at room temperature for 64 hours, diluted with ethyl acetate (100 mL), washed with water and brine. After being dried (Na2SO4), the organic solution was concentrated in vacuo. The residue was flash chromatographed on silica gel using 5% of acetone in dichloromethane as eluant to give the product (3.60 g, 75%).
