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).
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.
