Usage

General Description

N,N-Dimethyl-2,2-dimethoxy acetamide, also known as DMAA, is a chemical compound with the molecular formula C6H13NO3. It is commonly used as a solvent in pharmaceuticals and organic synthesis, as well as a reagent in chemical reactions. DMAA is a clear, colorless liquid with a faint odor and is soluble in water and organic solvents. It is also used as a stabilizer and inhibitor in the polymerization of vinyl chloride and as a corrosion inhibitor in metalworking fluids. DMAA is considered to have low acute toxicity, but its long-term effects on human health are not well studied. Therefore, proper handling and safety measures should be taken when working with this chemical.

Preparation method of zolpidem

The invention discloses a preparation method of a zolpidem intermediate. In the process of preparing the zolpidem intermediate N, N, 6-trimethyl-2-(4-methylphenyl)-imidazo [1, 2-alpha] pyridine-3-acetamide hydrochloride by reducing N, N, 6-trimethyl-2-(4-methylphenyl)-imidazo [1, 2-alpha] pyridine-3-acetamide hydrochloride, through process optimization and parameter adjustment, by using a 10% palladium-carbon catalyst and combining the reaction condition of hydrogen pressure of 0.02-0.09 MPa, the conversion effect of the N, N, 6-trimethyl-2-(4-methylphenyl)-imidazo [1, 2-alpha] pyridine-3-chloroacetamide hydrochloride is promoted, side reactions and impurities are reduced, the product yield is increased, the problem of low product synthesis yield in the process of preparing N, N, 6-trimethyl-2-(4-methylphenyl)-imidazo [1, 2-alpha] pyridine-3-acetamide hydrochloride through reduction reaction in zolpidem production is solved, and the production cost of zolpidem tartrate is reduced.

Process for the preparation of imidazopyridines

A process for the preparation of an imidazopyridine which is a compound of formula (I) STR1 in which: Y denotes hydrogen, a halogen or a C1-4 alkyl group; X1 and X2 denote, independently of each other, hydrogen, a halogen or a C1-4 alkoxy, C1-6 alkyl, CF3, CH3 S, CH3 SO2 or NO2 group; and R1 and R2 denote, independently of each other, hydrogen or a C1-5 alkyl group, with the proviso that R1 and R2 do not both denote hydrogen, or a salt thereof; which process comprises reacting a compound of formula (V) STR2 wherein Y, X1, X2, R1 and R2 are as defined above, with a reducing agent and if desired converting the resulting compound of formula (I) into a salt, together with intermediates of formulae: STR3 The final products have useful pharmacological properties, e.g. as anxiolytics.
