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 ...
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. [3] [4] [5]
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]

The Kulinkovich reaction describes the organic synthesis of substituted cyclopropanols through reaction of esters with dialkyldialkoxytitanium reagents, which are generated in situ from Grignard reagents containing a hydrogen in beta-position and titanium(IV) alkoxides such as titanium isopropoxide. [1]
The Conrad–Limpach synthesis is the condensation of anilines (1) with β-ketoesters (2) to form 4-hydroxyquinolines (4) via a Schiff base (3). The overall reaction type is a combination of both an addition reaction as well as a rearrangement reaction .
In the patented formation of 1-O-acetyl-2,3,5-tri-O-benzoyl-β-L-ribofuranose, a reactor containing thionyl chloride (5 ml) and methyl alcohol (100 ml) is stirred at 0–5 °C for 10 to 15 minutes. After this period, 10 g (ratio-wise) of ribose is added to the flask. The flask is then stirred and maintained at its temperature for 8 hours.
