Reaction Conditions

Reaction Steps

To a mixture of 4-iodoisoxazole (1 g, 5.13 mmol), 3-formylphenylboric acid (923 mg, 6.15 mmol) and sodium carbonate in DME/H2O/Toluene/EtOH (15 mL, 3/1/10/6, V/V) was added Pd(PPh3)4 (200 mg). The mixture was purged with N2 for 30 min and heated to 80° C. for 3 h. The reaction mixture was cooled followed by a standard aqueous/EtOAc workup and purified by prep-TLC (EA:PE=1:5) to give Intermediate 46 (12 mg, 1.5%).
