Synthesis of (R)-N2-(4-cyclopropyl-5-fluoro-6-methylpyridin-2-yl)-N4-(1, 5-dimethyl-1H-pyrazol-3-yl)-5-(3, 4-dimethylpiperazin-1-yl)pyrimidine-2,4-diamine (12). (R)-N2-(4-cyclopropyl-5-fluoro-6-methylpyridin-2-yl)-N4-(1,5-dimethyl-1H-pyrazol-3-yl)-5-(3-methylpiperazin-1-yl)pyrimidine-2,4-diamine hydrochloride (compound 9, 190 mg, 0.42 mmol) was taken in dichloromethane (2 ml) to give a yellow suspension. To this Hunig’s Base (0.184 ml, 1.05 mmol) was added and the suspension turned clear. After 10 min of stirring, reaction mixture turned into a white suspension and then it was concentrated to dryness. Resultant residue was dissolved in ethanol (absolute, 99.5%) (3 ml), and formaldehyde (0.042 ml, 0.63 mmol) was added and stirred for 10 min. To this clear solution, sodium cyanoborohydride (26.4 mg, 0.42 mmol) was added in one portion to get a white suspension. The reaction mixture was concentrated and the crude product was purified through reverse-phase chromatography to get the pure off-white solid of (R)-N2-(4-cyclopropyl-5-fluoro-6-methylpyridin-2-yl)-N4-(1, 5-dimethyl-1H-pyrazol-3-yl)-5-(3,4-dimethylpiperazin-1-yl)pyrimidine-2,4-diamine (80 mg, 40.8%).
