Reaktionsschritte

To a solution of dibenzyl 3,4,5-trimethoxyphenylphosphonate 2 (1 mmol) in 30 mL of ethyl acetate is added 10% Pd on carbon (0.10 g). The mixture is stirred under an atmosphere of hydrogen for 16 hours. Mixture is filtered through celite and washed with methanol (3×10 mL). All washings and filtrate are combined and concentrated to give 3,4,5-trimethoxyphenylphosphonic acid 3.
