Embodiment 1
[0241] (2R)-2-({5-chloro-2-[(5-cyclopropyl-1H-pyrazol-3-yl)amino]pyrimidin-4-yl}amino)-2-(4-fluoro Phenyl)ethanol
[0242] To a microwave vial (Personal Chemistry) was added (2R)-2-[(2,5-dichloropyrimidin-4-yl)amino]-2-(4-fluorophenyl)ethanol (Method 1, 250 mg, 0.83 mmol), 5-cyclopropyl-1H-pyrazol-3-amine (204 mg, 1.66 mmol), DIPEA (0.17 mL, 0.97 mmol) and n-butanol (2 mL). The reaction mixture was heated to 160°C and maintained for 5 hours. Solvent was removed. The white solid was purified by semi-preparative HPLC (Gilson) to give the title compound (43 mg, 13%). 1 H NMR (300MHz, DMSO-d6) δ0.76(m, 2H), 0.97(m, 2H), 1.87(m, 1H), 3.73-3.85(m, 2H), 5.22(m, 2H), 7.13( m, 2H), 7.47 (m, 2H), 7.97 (d, 1H), 8.28 (s, 1H).
Embodiment 2-8
