Procedure

A mixture of 4-chloro-2-(2-pyridinyl)-6-(trifluoromethyl)pyrimidine (25 mg, 0.096 mmol), m-phenetidine (19 μl, 0.144 mmol), and 2N HCl (75 μl) in water:ethanol (2:1, 5 ml) was refluxed for 24 h. The mixture was cooled to room temperature and basified with aqueous 2N NaOH to pH 10-12. The resulting precipitate was filtered, washed with water, water:ethanol (2:1) and dried to give a yellow solid (22 mg, 63%). 1H NMR (CDCl3): 8.88-8.85 (m, 1H), 8.58 (d, J=8.1 Hz, 1H), 7.93-7.88 (m, 1H), 7.61 (s, 1H), 7.48-7.44 (m, 1H), 7.35 (t, J=8.4 Hz, 1H), 7.05 (s, 1H), 6.89-6.81 (m, 3H), 4.07 (q, J=7.1 Hz, 2H), 1.45 (t, J=7.1 Hz, 3H).
