  • Patent number: 8552195
    Abstract: The method in accordance with the present invention has: mixing E2M, an organic solvent, a weak base, sodium dithionite, and a phase transfer catalyst to obtain an E2M mixture solution; heating the E2M mixture solution and adding water to obtain a heated E2M aqueous solution having an organic layer; and extracting the organic layer from the heated E2M aqueous solution, and condensing and drying the organic layer to obtain donepezil. Employing sodium dithionite as a reducing agent improves safety over hydrogen gas used in conventional methods and lowers the cost in contrast to the conventional noble metal catalysts that are extremely expensive. Furthermore, the method of the present invention requires only 60 minutes of reaction time to synthesize donepezil with a promising yield more than 85%, which greatly raises the efficiency and economic value of the manufacture of donepezil.

  • Patent number: 5596095
    Abstract: The present invention is a method of protecting a sulfonic acid functional group in an organic molecule as a substituted or unsubstituted neopentyl sulfonate ester. The method allows the conversion of R--SO.sub.3 --H to R'--SO.sub.3 --H, wherein R and R' are different organic radicals. Also disclosed is a method of increasing the bioavailability of drugs with a sulfonic acid functional group by protecting the sulfonic acid functional group as a substituted neopentyl sulfonate ester which has a masked heteroatom nucleophile. The masked nucleophile can be liberated in vivo, resulting in removal of the neopentyl protecting group and regeneration of the parent drug.

  • Patent number: 5231104
    Abstract: A series of novel 1-(phenethyl) and 1-(2-heteroarylethyl)-3-substituted piperidine derivatives have been prepared, including their pharmaceutically acceptable salts and various novel key intermediates therefor. The 3-substituent present in these compounds is an unsubstituted or substituted diphenylmethoxy group or a diphenylmethoxy-derived group, while the 1-substituent is unsubstituted or substituted phenethyl or 1-(2-heteroarylethyl) wherein the heteroaryl moiety is thienyl, pyridyl or pyrazinyl. These compounds in the form of both their racemates and 3R-isomers, are useful in therapy as smooth muscle muscarinic receptor antagonists and therefore, are of value in the treatment diseases associated with altered motility and/or smooth muscle tone.

  • Patent number: 4450274
    Abstract: This invention pertains to a new process for preparing an ethambutol-sulfonic acid derivative which is widely used as an antituberculosis agent. In the known process, there are many defects which include: side reactions, impurities, low yield, high cost production inefficiency and pollution hazard.For the purpose of preparing an ethambutol-sulfonic acid derivative of a higher purity and higher yield than the known process, ethambutol or its hydrogen chloride salt is reacted with chloromethane sulfonic acid or its sodium salt in the lower alcoholic solvent such as methanol, ethanol, propanol, or isopropanol, at a temperature between room temperature and boiling point of the solvent, for about an hour, to produce ethambutol-chloromethane-sulfonate which is then reacted with isoniazid to produce the ethambutol-sulfonic acid derivative of the present invention.
