실험 절차

A mixture of tert-butyl 3-(3-amino-2-chloro-5-cyanophenyl)azetidine-1-carboxylate (Example 357D)(154 mg, 0.500 mmol), 2-chloro-4-(ethyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (Intermediate 10)(172 mg, 0.500 mmol), Cs2COs (326 mg, 1.00 mmol), DPPF (27.7 mg, 0.050 mmol), 4,5-bis(diphenylphosphino)-9,9-dimethyxanthene (29 mg, 0.050 mmol), and Pd(OAc)2 (34 mg, 0.150 mmol) in a microwave vial was flushed with nitrogen. Dioxane (5 mL) was added and vial was sealed and heated at 100° C. for 3 hr. After cooling to room temperature, the reaction was partitioned between EtOAc and water and then filtered through celite. The solvent was removed and radial silica gel chromatography eluting with hexane containing 5 to 40% EtOAc afforded tert-butyl 3-(2-chloro-5-cyano-3-((7-cyano-4-(ethyl(4-methoxybenzyl)amino)-imidazo[2,1-f][1,2,4]triazin-2-yl)amino)phenyl)azetidine-1-carboxylate (207 mg, 67% yield) as a foam. It was dissolved in DCM (0.6 mL) and anisole (30 μL, 0.272 mmol) and TFA (0.4 mL) were added. After 2 hr, the solvent was removed and the residue was applied onto an SCX cartridge using a 1:1 mixture of DCM and MeOH. This was washed with MeOH and eluted with a 1:1 mixture of 1N NH3 in MeOH and DCM to give crude 2-((3-(azetidin-3-yl)-2-chloro-5-cyanophenyl)amino)-4-(ethylamino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (70 mg). A sample was purified by preparative HPLC (Column: Waters XBridge C18, 19×200 mm, 5-μm particles; Mobile Phase A: water with 20-mM ammonium acetate; Mobile Phase B: 95:5 methanol: water with 20-mM ammonium acetate; Gradient: 25-65% B over 20 minutes, then a 5-minute hold at 100% B; Flow: 20 mL/min) to give the title compound. This was converted to the mono HCl salt.
