A mixture of 4-chloro-6-cyclopropyl-2-(2-trifluoromethylphenyl)-pyrimidine (7.00 g, 23.4 mmol, prepared as described above in example 8) and 1H-pyrazolo[3,4-b]pyridin-3-ylamine (9.43 g, 70.3 mmol) in N-methylpyrrolidinone (50 mL) was heated at 130° C. for 12 hours. The residue was cooled, dissolved in N-methylpyrrolidinone (2 mL), poured into water (500 mL) and sodium bicarbonate (15 mL) then filtered, washing with water. Purification by flash chromatography [SiO2, ethyl acetate:hexanes (35:65)] provided the title compound (5.25 g, 57% yield) as a white solid. 1H-NMR (500 MHz, DMSO-d6) δ 13.1 (br s, 1H), 10.5 (br s, 1H), 8.50 (m, 2H), 7.82 (d, J=7.8 Hz, 1H), 7.73 (m, 3H), 7.66 (t, J=7.7 Hz, 1H), 7.12 (m, 1H), 2.07 (m, 1H), 1.02 (m, 2H), 0.97 (m, 2H) ppm; LC-MS 397.22 (M+H); Rt (Method A) 3.412 minutes.
