实验过程
4-Amino-1,2,2,6,6-pentamethylpiperidine (1 g) and 2,6-dichloro-5-fluoropyrimidine (1.5 g) were dissolved in methanol (10 mL). The reaction solution was stirred at room temperature overnight. The reaction solution was evaporated and crystallized from ethyl acetate and hexanes to give 2-chloro-5-fluoro-N4-(1,2,2,6,6-pentamethylpiperidin-4-yl)-4-pyrimidineamine HCl salt (1.65 g, 93%). 1H NMR (DMSO-d6): δ 1.38 (s, 6H), 1.48 (s, 6H), 2.02 (m, 4H), 2.68 (d, J=4.8 Hz, 3H), 4.33 (br, 1H), 8.10 (d, J=3.3 Hz, 1H), 8.32 (d, J=6.9 Hz, 1H), 9.66 (br, 1H).
