Procedure

To a stirring solution of 4-bromo-1-nitro-2-(propan-2-ylsulfonyl)benzene (0.44 g, 1.6 mmol) and Dimethyl Phosphine oxide (0.15 g, 1.9 mmol) in 1 mL of DMF, was added Potassium Phosphate (0.37 g, 1.8 mmol), Pd(OAc)2 (18 mg, 0.08 mmol), Xanphos (55 mg, 0.10 mmol). The reaction mixture was stirred at 110 degrees C. overnight. The reaction mixture was cooled to room temperature and filtered through celite. The desired product was isolated through prep-HPLC to yield a brownish yellow solid (0.24 g, 55% yield)
