Reaction Steps

3b (1.0 g, 2.4 mmol), benzophenone imine (0.4 mL, 2.4 mmol), sodium tert-butoxide (350 mg, 3.6 mmol), BINAP (150 mg, 0.27 mmol), and Pd2dba3 (55 mg, 0.06 mmol) were dissolved in toluene (10 mL) and degassed for 10 minutes with N2. The reaction was then sealed and heated to 80° C. for 2 hours. After cooling to room temperature, the reaction was diluted with EtOAc and brine, and the aqueous layer was extracted with EtOAc. The combined organic layers were dried over MgSO4, filtered, and concentrated, and the residue was purified by silica gel chromatography (30% EtOAc in hexanes) to give the desired product, 3c.
