Procedure

A mixture of crude 4-chloro-2-[6-(trifluoromethyl)-3-pyridinyl]-6-(trifluoromethyl)pyrimidine (50 mg, 0.152 mmol), 2-chloro-5-methoxyaniline (50 mg, 0.229 mmol) and 2N HCl (150 μl) in water:ethanol (2:1, 10 ml) was refluxed for 120 h. The mixture was cooled to room temperature and basified with aqueous 2N NaOH to pH 10–12. The mixture was extracted with ethyl acetate (75 ml), washed with water (2×20 ml), with aqueous saturated NaCl (1×20 ml) and dried over anhydrous sodium sulfate. The ethyl acetate solution was rotary evaporated to dryness and the residue was purified by preparative TLC to give a white solid (3 mg, 4%). 1H NMR (CDCl3): 9.72 (s, 1H), 8.90 (dd, J=3.0, 7.8 Hz, 1H), 7.81 (d, J=8.1 Hz, 1H), 7.75 (s, 1H), 7.40 (d, J=9.3 Hz, 1H), 7.36 (s, 1H), 6.99 (s, 1H), 6.75 (dd, J=3.0, 8.7 Hz, 1H), 3.86 (s, 3H).
