Reaktionsschritte
2,6-diisopropylphenol was treated with bromochloromethane in the presence of sodium hydroxide and THF to give an 85% yield of O-chloromethyl-2,6-diisopropylphenol, which was purified by vacuum distillation. Treatment of O-chloromethyl-2,6-diisopropylphenol with phosphoric acid and triethylamine in acetonitrile followed by solvent removal, dissolution in methanol, pH adjustment and precipitation with acetone gave an 85% yield of phosphono-O-methyl 2,6-diisopropylphenol disodium salt.
