Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: To a solution of 2-(Propane-1-sulfonyl)-phenylamine (3.69 g, 18.5 mmol) of N,N-dimethylformamide (40 mL), sodium hydride (1.48 g, 37 mmol) is added portionwise at 0° C. After stirring, 2,4,5-trichloropyrimidine (2.1 mL, 18.5 mmol) is added. The mixture is stirred at 0° C. for 30 minutes and is further stirred at room temperature for 7 hrs. After adding saturated aqueous ammonium chloride, the mixture is poured into water and extracted twice with ethyl acetate. The organic layer is washed with brine, dried over sodium sulfate, and evaporated in vacuo. The residue is purified by silica gel column chromatography (n-hexane-ethyl acetate gradient) to afford the title compound as colorless solids. The mixture is stirred at 0° C. for 30 minutes is further stirred at room temperature for 7 hrs extracted twice with ethyl acetate The organic layer is washed with brine dried over sodium sulfate evaporated in vacuo The residue is purified by silica gel column chromatography (n-hexane-ethyl acetate gradient)
