실험 절차
To 3-fluoro-4-(5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridin-2-yl)benzenamine (206 mg, 0.570 mmol) and (R)-tert-butyl 2,5-dioxo-tetrahydrofuran-3-ylcarbamate (123 mg, 0.570 mmol) was added benzene (5.7 mL) and acetic acid (163 μl, 2.85 mmol) before it was stirred at 80° C. for 1 h. The two regioisomers were separated via SFC (Column: Princeton Pyridine, Mobile Phase: 60:40 liquid CO2/MeOH) to give (3R)-3-(tert-butoxycarbonylamino)-4-(3-fluoro-4-(5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridin-2-yl)phenylamino)-4-oxobutanoic acid and its regioisomer. MS (ESI) m/z: Calculated: 576.2; Observed: 577.1 (M++H).
