Reaction Steps

The title compound was prepared from a mixture of 4-chloro-2-(3-pyridinyl)-6-(trifluoromethyl)pyrimidine (50 mg, 0.193 mmol), 3-aminophenol (32 mg, 0.290 mmol), and 2N HCl (150 μl) in water:ethanol (2:1, 10 ml) was refluxed for 24 h. The mixture was cooled to room temperature and the resulting crystals was filtered, washed with water, with water:ethanol (2:1) and dried to give a tan crystals (22 mg, 30%). 1H NMR (DMSO-d6): 10.17 (s, 1H), 9.36 (d, J=1.5 Hz, 1H), 8.72–8.66 (m, 2H), 7.66–7.62 (m, 1H), 7.20 (s, 1H), 7.10 (d, J=7.8 Hz, 1H), 7.05 (d, J=7.8 Hz, 1H), 7.04 (s, 1H), 7.01 (s, 1H), 6.45–6.41 (m, 1H).
