Procedure

A mixture of 4-chloro-2-(2-pyrazinyl)-6-(trifluoromethyl)pyrimidine (50 mg, 0.192 mmol), 2,5-dimethoxyaniline and aqueous 2N HCl (150 μl) in water:ethanol (1:1, 10 ml) was refluxed for 48 h. The mixture was cooled to room temperature and then basified with aqueous 2N NaOH to pH 10–12. The resulting precipitate was filtered, washed with water, water:ethanol (2:1) and isolated as a green-yellow solid (46 mg, 64%). 1H NMR (CDCl3): 9.74 (d, J=1.5 Hz, 1H), 8.79 (dd, J=1.8, 2.4 Hz, 1H), 8.72 (d, J=2.4 Hz, 1H), 7.80 (bs, 1H), 7.70 (s, 1H), 7.07 (s, 1H), 6.91 (d, J=9.3 Hz, 1H), 6.72 (dd, J=3.0, 9.0 Hz, 1H), 3.87 (s, 3H), 3.86 (s, 3H).
