Potassium Phosphate, Tribasic → (4-Amino-3-chlorophenyl)dimethylphosphine oxide

Participants

Reaction Steps

To a solution of 2-chloro-4-iodoaniline (0.507 g, 2.00 mmol) in 8 mL DMF was added dimethylphosphine oxide (0.171 g, 2.20 mmol), palladium acetate (22.4 mg, 0.0100 mmol), XANTPHOS (69.4 mg, 0.120 mmol), and potassium phosphate (0.467 g, 2.20 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 (0-20% 7N ammonia in methanol:dichloromethane) to afford the desired product (0.340 g, 83% yield).
