Txheej txheem ntau lawm: Gallic acid tau esterified nrog methanol catalyzed los ntawm sulfuric acid los tsim methyl 3,4, 5-trihydroxybenzoate, thiab ces methylated nrog dimethyl sulfate kom tau methyl 3-methoxy-4, {{5} } phau ntawv tshuaj dihydroxybenzoate, uas tom qab ntawd condensed nrog diiodomethane nyob rau hauv cov xwm txheej yooj yim los tsim methyl 5-methoxy-3, 4-dioxy-methylene benzoate. Thaum kawg, cov khoom tau npaj los ntawm bromination.
