Reaction Steps

(+/−)-2-((3-((3R,4R)-4-amino-3-hydroxypiperidin-1-yl)-2-chloro-5-cyanophenyl)amino)-4-(ethyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile (29 mg, 0.046 mmol) was dissolved in DMF (1 ml) in a 4 ml vial. DIPEA (0.25 ml, 1.431 mmol) was added and the mixture warmed to 70° C. A solution of 2-(chloromethyl)oxirane (100 μl, 1.279 mmol) in DMF (1 ml) was added slowly. The reaction mixture was kept at 70° C. for 30 minutes. The crude reaction mixture was filtered through a MCX cartridge (Waters, 5 g adsorbent). The cartridge was washed with MeOH and the product eluted with a 1:1 mixture of (CH3CN+2 molar solution of NH3 in MeOH). Evaporation to dryness gave 30 mg of (+/−)-2-((2-chloro-5-cyano-3-((3R,4R)-3-hydroxy-4-(3-hydroxyazetidin-1-yl)piperidin-1-yl)phenyl)amino)-4-(ethyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile. The crude was used “as is” in the following deprotection
