Participants

Reaction Steps

To a solution of methyl 21-(2-hydroxy-3,4-dimethoxy-6-methylbenzoyl)heneicosanoate in acetic acid is added perchloric acid and catalytic reduction is carried out with 5% palladium-on-carbon. The reaction mixture is worked up as in the corresponding step of Reference Example 2 and the resultant product is recrystallized from ethanol. The above procedure yields methyl 22-(2-hydroxy-3,4-dimethoxy-6-methylphenyl)docosanoate as colorless needles, m.p. 71° C.-72.5° C.
