Procedure

1-Iodo-3-nitrobenzene (249 mg, 1 mmol) was dissolved in 10 mL of acetonitrile. Tetrakis(triphenylphosphine)palladium (58 mg, 3 mol %), dimethyl phosphite (0.138 ml, 1.5 mmol) and triethylamine (0.28 ml, 2 mmol) were added thereto and stirred at 70° C. overnight. After removing a solvent, the mixture was purified in accordance with the purification process A to obtain a mixture (0.222 g) of monomethyl (3-nitrophenyl) phosphonate and dimethyl ester. The obtained monomethyl phosphonate was dissolved in 10 mL of methanol. Pd/C in catalyst quantity was added thereto and stirred under hydrogen atmosphere overnight. After filtering out the catalyst, a solvent was removed to obtain a mixture of monomethyl (3-aminophenyl) phosphonate and dimethyl ester.
