実験手順

(+/−) Tert-butyl (2-chloro-7-cyanoimidazo[2,1-f][1,2,4]triazin-4-yl)(cyclopropyl)carbamate (Intermediate 1) (30 mg, 0.090 mmol), 3-amino-4-chloro-5-(3-(morpholine-4-carbonyl)-4-(oxetan-3-yl)piperazin-1-yl)benzonitrile (36.4 mg, 0.090 mmol), palladium (II) acetate (6.04 mg, 0.027 mmol), dppf (4.97 mg, 8.96 pimp, Xantphos (5.19 mg, 8.96 μmol), and cesium carbonate (52.6 mg, 0.161 mmol) were combined in a 10 ml flask and Dioxane (1 mL) was added. The flask was evacuated and backfilled with N2 3×, then heated at 100° C. for 1 h. The reaction was cooled to rt and filtered through celite, rinsing with EtOAc. The solvent was removed in vacuo and the crude material was purified by flash column (0-5% MeOH/DCM). (+/−) Tert-butyl (2-((2-chloro-5-cyano-3-(3-(morpholine-4-carbonyl)-4-(oxetan-3-yl)piperazin-1-yl)phenyl)amino)-7-cyanoimidazo[2,1-f][1,2,4]triazin-4-yl)(cyclopropyl)carbamate (45 mg) was obtained as a yellow glass.
