실험 절차

(+/−)-2-((2-chloro-5-cyano-3-((4aR,8aR)-2-oxohexahydro-1H-pyrido[3,4-b][1,4]oxazin-6(7H)-yl)phenyl)amino)-4-(ethyl(4-methoxybenzyl)amino)imidazo[2,1-f][1,2,4]triazine-7-carbonitrile was taken up in DCE (0.8 mL), anisole (0.043 mL, 0.391 mmol) and TFA (0.5 mL, 6.49 mmol). The mixture stirred 2 h at 25° C. and solvent was removed. The crude material was purified via preparative LC/MS with the following conditions: Column: Waters XBridge C18, 19×200 mm, 5-μm particles; Guard Column: Waters XBridge C18, 19×10 mm, 5-μm particles; Mobile Phase A: water with 20-mM ammonium acetate; Mobile Phase B: 95:5 acetonitrile: 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. Fractions containing the desired product were combined and dried via centrifugal evaporation to afford (+/−)-N-((3R,4R)-1-(3-amino-2-chloro-5-cyanophenyl)-3-hydroxypiperidin-4-yl)-2-chloroacetamide (2.2 mg).
