Procedure

A Schlenk tube was charged with 2-chloro-N-((8-chloro-2-(2-chlorophenyl)-quinolin-3-yl)methyl)-5-fluoropyrimidin-4-amine (0.1027 g, 0.2368 mmol), benzophenone imine (0.04751 ml, 0.2842 mmol), tris(dibenzylideneacetone)-dipalladium (0) (0.05421 g, 0.05920 mmol), rac-2,2-bis(diphenylphosphino)-1,1-binaphthyl (0.1106 g, 0.1776 mmol), sodium tert-butoxide (0.03186 g, 0.3315 mmol), and 2 ml of toluene, and the mixture was purged with argon and stirred at 80° C. After 19.5 hr, the mixture was cooled to room temperature and diluted with Et2O (40 ml), filtered, rinsed with Et2O (40 ml), and concentrated under reduced pressure to give N4-((8-chloro-2-(2-chlorophenyl)quinolin-3-yl)methyl)-N2-(diphenylmethylene)-5-fluoropyrimidine-2,4-diamine as an orange syrup: LC-MS m/z 578.0 and 580.1 [M+H]+. The orange syrup was carried on crude without purification for the next step.
