실험 절차

A mixture of rac-1-(5-fluoropyrimidin-2-yl)ethanamine hydrochloride (Method 1, 100 mg), 2,5-dichloro-N-(5-methyl-1H-pyrazol-3-yl)pyrimidin-4-amine (Method 9, 200 mg) and DIPEA (0.150 ml) in n-BuOH (2.5 ml) was charged into a microwave reaction vessel. The vessel was sealed and heated in microwave reactor at 180° C. for 6 hours. The solvent was removed under reduced pressure and the residue was purified by Gilson (10-50% MeCN/H2O, 15 min) to give 5-chloro-N2-[1-(5-fluoropyrimidin-2-yl)ethyl]-N4-(5-methyl-1H-pyrazol-3-yl)pyrimidine-2,4-diamine as solid (55 mg). The tile compound was obtained after chiral purification using SFC conditions (Chiralpak AD-H, 20% i-PrOH/80% CO2/0.1% Dimethylethylamine). 1H NMR (300 MHz, DMSO-d6) δ 12.03 (s, 1H) 8.83 (s, 2H) 7.88 (s, 1H) 7.44 (s, 1H) 5.93 (s, 1H) 4.92-5.29 (m, 1H) 2.20 (s, 3H) 1.49 (d, 3H); m/z 350.
