Procedure

A round-bottomed flask was charged with 2,4,5-trichloropyrimidine (5 mL, 43.6 mmol), ethyl 2-aminobenzoate (7.6 g, 46.0 mmol), di-isopropyl-ethylamine (8.3 mL, 48.0 mmol) and ethanol (60 mL). The flask was fitted with a reflux condenser and the reaction was heated to reflux and stirred for 18 h. A white solid appeared in the reaction mixture. The reaction was cooled to room temperature, and the solid was filtered off and washed with ethanol (100 mL), ethanol/hexane (1:1, 200 mL) and hexane (200 mL) to afford the product (10.2 g, 32.7 mmol, 75% yield) as a white solid. MS: M(C13H11Cl2N3O2)=312.15, (M+H)+=312.0 and 314.0.
