A mixture of 4-chloro-6-methyl-2-(2-trifluoromethyl-phenyl)-pyrimidine (0.10 g, 0.37 mmol) and 5-fluoro-1H-indazole-3-ylamine (0.072 g, 0.48 mmol) was heated neat at 160-170° C. for 8 hours. The resulting residue was cooled to ambient temperature then dissolved in N-methyl-pyrrolidinone (2 mL). This mixture was poured into water (20 mL) and sodium bicarbonate (5 mL) was added and the resulting mixture filtered, washing with water. Purification by preparative HPLC provided the title compound (0.081 g, 43% yield) as a tan solid. 1H-NMR (500 MHz, DMSO-d6) δ 12.8 (br s, 1H), 10.6 (br s, 1H), 7.86 (d, J=8.0 Hz, 1H), 7.77 (m, 4H), 7.62 (br s, 1H), 7.50 (m, 1H), 7.29 (m, 1H), 2.44 (s, 3H) ppm; LC-MS 388.05 (M+H); Rt (Method A) 2.900 minutes.
