Trimethobenzamide synthesis: Hoffmann La Roche, U.S. patent 2,879,293 (1959). Alkylation of the sodium salt of p -hydroxybenzaldehyde (1) with 2-dimethylaminoethyl chloride affords the ether (2). Reductive amination of the aldehyde in the presence of ammonia gives diamine (3).
Synthesis. Eudesmic acid is most directly synthesized by reaction of gallic acid with dimethyl sulfate. [2] ... Trimethobenzamide; Trimetozine; Tritiozine ...
Benzamide is an organic compound with the chemical formula of C 7 H 7 NO.It is the simplest amide derivative of benzoic acid.In powdered form, it appears as a white solid, while in crystalline form, it appears as colourless crystals. [5]
3,4,5-Trimethoxybenzaldehyde can be used as an intermediate in the synthesis of some pharmaceutical drugs including trimethoprim, [1] [2] cintriamide, roletamide, trimethoquinol (aka tretoquinol), and trimazosin as well as some psychedelic phenethylamines.

DMTMM (4-(4,6-dimethoxy-1,3,5-triazin-2-yl)-4-methyl-morpholinium chloride) is an organic triazine derivative commonly used for activation of carboxylic acids, particularly for amide synthesis. Amide coupling is one of the most common reactions in organic chemistry and DMTMM is one reagent used for that reaction.
The synthesis consists of three steps. In the first step, 2-iodobenzoic acid is oxidized by sodium periodate and cyclized to 1-hydroxy-1,2-benziodoxol-3(1H)-one.The target compound can then be obtained by acylation with acetic anhydride and subsequent substitution reaction with trifluoromethyltrimethylsilane.
This reagent was originally prepared by Conrad Willgerodt [3] by reacting iodobenzene with a mixture of acetic acid and peracetic acid: [4] [5]. C 6 H 5 I + CH 3 CO 3 H + CH 3 CO 2 H → C 6 H 5 I(O 2 CCH 3) 2 + H 2 O
