Reaction Steps
Methyl 4-(bromomethyl) benzoate (compound 47) (11.2 g, 49 mmol) was dissolved in 25 mL trimethyl phosphite and refluxed under N2 for 5 hrs. Excess trimethyl phosphite was removed by co-distillation with toluene to give crude 4-(Dimethoxy-phosphorylmethyl)-benzoic acid methyl ester (compound 48).
