Procedure

To a solution of 5-chloro-2-nitroanisole (1.00 g, 5.33 mmol) in 20 mL DMF was added diethyl phosphite (0.809 g, 5.86 mmol), palladium acetate (0.060 g, 0.27 mmol), XANTPHOS (0.185 g, 0.320 mmol), and potassium phosphate (1.24 g, 5.86 mmol). The mixture was purged with nitrogen, and subjected to microwaves at 150° C. for 20 minutes. The reaction mixture was concentrated and purified by silica gel chromatography (0-45% ethyl acetate:heptane) to afford the desired product (0.504 g, 33% yield).
