Reaction Steps

To a solution of 4-Piperazin-1-ylmethyl-benzoic acid (4c) and chloro-(dimethyl-phosphinoyl)-methane (5a) in ethanol was added potassium carbonate. The resulting reaction mixture was refluxed, then cooled to room temperature, diluted with brine, acidified to pH˜4, and extracted with EtOAc until the aqueous layer showed little or no evidence of product by HPLC. The combined organics were dried over MgSO4 and concentrated on rotary evaporator. The desired product was purified by silica gel flash chromatography.
