Referential Example 5 2-Chloro-N-(5-cyclopropyl-lH-pyrazol-3-yl)-6-methylpyrimidin-4-amine (189) A mixture of 5-cyclopropyl-lH-pyrazol-3 -amine (1.98 g, 16.07 mmol), 2,4-dichloro-6-methyl-pyrimidine (2.62 g, 16.07 mmol), DIPEA (5.7 mL, 32.15 mmol) and anhydrous EtOH (50 mL) was stirred at 70 oC under N2 for 3 d. The reaction mixture was cooled and poured into water (ca. 700 mL). The reaction was stirred at RT overnight until solid precipitated out. The solid was filtered, washed with additional water and pumped dry under high- vacuum to afford 2.37 g (59%) of 189 as a solid: 1H NMR (400 MHz, DMSO-i/6) delta 12.12 (s, 1H), 10.08 (s, 1H), 7.04 (br s, 1H), 5.93 (br s, 1H), 2.27 (s, 3H), 1.93 to 1.84 (m, 1H), 0.96 – 0.88 (m, 2H), 0.70 – 0.64 (m, 2H).
