Proses dull cynhyrchu: Cafodd asid galig ei esterified â methanol wedi'i gataleiddio gan asid sylffwrig i gynhyrchu methyl 3,4, 5-trihydroxybenzoate, ac yna ei fethylu â sylffad dimethyl i gael methyl 3-methoxy-4, {{5} }llyfr cemegol dihydroxybenzoate, a gafodd ei gyddwyso wedyn â diiodomethan o dan amodau sylfaenol i gynhyrchu methyl 5-methoxy-3, 4-dioxy-methylene benzoate. Yn olaf, paratowyd y cynnyrch trwy brominiad.
