A. Martin et al., Synthesis of methylamino-2-phenyl-2-butyl-3,4,5-trimethoxybenzoate, the main bioactive metabolite of trimebutine maleate, ARZNEI-FOR, 50(6), 2000, pp. 544-549
The first synthesis of the methylamino-2-phenyl-2-butyl-3,4,5-trimethoxyben
oate (desmethyl- trimebutine) I is described. This compound is the main bio
active metabolite of trimebutine II (Debridat(R), CAS 39133-31-8), an antis
pasmodic widely used for intestinal diseases since 1969. It was used for ph
armacokinetic and bioequivalence studies.
