实验步骤: 2,4,6-trifluorobenzylamine (5 g, 31 mmol) was added dropwise to a stirred suspension of 2,4-dichloropyrimidine (4.6 g, 31 mmol) and DIPEA (5.4 mL, 62 mmol) in IPA (100 mL) at 0° C. then the reaction mixture was warmed to room temperature and stirred overnight. The precipitate was collected and washed with diethyl ether to afford the first crop of 2-chloro-N-(2,4,6-trifluorobenzyl)pyrimidin-4-amine IV-1. The filtrate was concentrated and purified by column chromatography (0-30% v/v ethyl acetate/petrol) to afford a second crop (total yield 5.3 g, 62%). LC-MS (Method F), RT=2.27 min. (ES+) 274. The precipitate was collected washed with diethyl ether
