Reaction Steps

To a solution of O-methoxymethyl-β-hydroxytyrosine (21.0 g) in 1N-sodium hydroxide (250 ml) was added dimethylsulfate (16.5 g). After stirring for 20 min. at 90° C., the solution was acidified with diluted hydrochloric acid in ice bath. The acidic solution was washed with diethyl ether and adjusted to pH 6.0 with 1N-sodium hydroxide. After evaporation, the solid was collected by filtration to give O-methoxymethyl-N-methyl-β-hydroxytyrosine (5.2 g).
