実験手順

A 25 mL round-bottomed flask was charged with tert-butyl 4-(2-(5-(3-methoxy-3-oxopropylthio)-3-phenoxypyridin-2-ylamino)thiazol-4-yl)piperidine-1-carboxylate (500 mg, 0.876 nmol), 7-chlorothieno[3,2-b]pyridine (178 mg, 1.05 mmol), and DMSO (8 mL). Nitrogen was bubbled through the solution for 10 minutes. Potassium 2-methylpropan-2-olate (295 mg, 2.63 mmol) was added and stirred at room temperature for 30 minutes. The reaction was poured into saturated aqueous NH4Cl and extracted with EtOAc (2×20 mL). The organic layer was dried with sodium sulfate, filtered and concentrated. The residue was purified on silica (50% EtOAc in hexanes) to afford tert-butyl 4-(2-(3-phenoxy-5-(thieno[3,2-b]pyridin-7-ylthio)pyridin-2-ylamino)thiazol-4-yl)piperidine-1-carboxylate.
