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).
