実験手順

A slurry of potassium phosphate (2.50 g, 11.8 mmol), (Amphos)2PdCl2 (0.125 g, 0.177 mmol), 2-(2-fluoro-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenyl)-5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridine (2.78 g, 5.89 mmol) and (S)-1-tert-butyl 2-methyl 4-(trifluoromethylsulfonyloxy)-1H-pyrrole-1,2(2H,5H)-dicarboxylate (2.21 g, 5.89 mmol, synthesized according to literature reference: Bioorganic and Medicinal Chemistry Letters, 2007, 2715) in 15 mL DMF was flushed with argon, sealed, and heated to 80° C. After 6 h, the reaction was judged complete, cooled, and filtered through celite, rinsing with 200 mL EtOAc. The filtrate was washed with water, brine, dried over sodium sulfate, filtered, and concentrated in vacuo. Purification by silica gel chromatography, EA/hexanes gradient, gave (2S)-1-tert-butyl 2-methyl 4-(3-fluoro-4-(5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridine-2-yl)phenyl)-2H-pyrrole-1,2(5H)-dicarboxylate as a light yellow solid. MS (ESI) m/z: Calculated: 571.2; Observed: 572.1 (M++1).
