Reaction Steps

3,4,5-Trimethoxybromobenzene is prepared following the procedure of Tetrahedron Lett. 26 (1985):5939-5942. Dibenzyl phosphite is heated in the presence of tetrakis(triphenylphosphine)palladium (0), triethylamine and toluene with 3,4,5-trimethoxybromobenzene to give Dibenzyl 3,4,5-trimethoxyphenylphosphonate 2 following the procedure of J. Med. Chem. 32 (1989):1580-1590.
