반응 단계

To 3-fluoro-4-(5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridin-2-yl)benzenamine (183 mg, 0.506 mmol) and 3-oxocyclobutanecarboxylic acid (63.5 mg, 0.557 mmol) in DCM (2.5 mL) and triethylamine (212 μl, 1.519 mmol) was added titanium(IV) chloride in DCM (0.759 ml, 0.759 mmol) at ambient temperature. The reaction mixture was concentrated, suspended in water, filtered, washed with water, and dried in a vacuum oven to give 3-((3-fluoro-4-(5-(1-phenyl-cyclopropyl)[1,3]thiazolo[5,4-b]pyridin-2-yl)phenyl)amino)cyclobutanecarboxylic acid as yellow solid. MS (ESI) m/z: Calculated: 459.1; Observed: 460.4 (M++H).
