Diethyl 4,4'-dimethyl-2,2'-bithiazole-5,5'-dicarboxylate is a chemical compound with the molecular formula C13H14N2O4S2. It is a white crystalline solid that is soluble in organic solvents such as ethanol, acetone, and dichloromethane. diethyl 4,4?-dimethyl-2,2?-bithiazole-5,5?-dicarboxylate is characterized by its unique structure, featuring a bithiazole core with two methyl groups at the 4-position and two ester groups at the 5-position, which are connected to the ethyl groups. It is synthesized through a series of chemical reactions, including the condensation of 2-amino-4-methylthiazole-5-carboxylic acid with diethyl oxalate. Diethyl 4,4'-dimethyl-2,2'-bithiazole-5,5'-dicarboxylate has potential applications in the pharmaceutical and chemical industries, particularly as an intermediate in the synthesis of various organic compounds and as a building block for the development of new materials.

3944-31-8 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 3944-31-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 3,9,4 and 4 respectively; the second part has 2 digits, 3 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 3944-31:
(6*3)+(5*9)+(4*4)+(3*4)+(2*3)+(1*1)=98
98 % 10 = 8
So 3944-31-8 is a valid CAS Registry Number.

METHOD FOR PRODUCING PHENYL-SUBSTITUTED HETEROCYCLIC DERIVATIVE BY MEANS OF COUPLING METHOD USING PALLADIUM COMPOUND

-

Paragraph 0316; 0317; 0318, (2013/06/28)

The present invention provides a method for producing a xanthine oxidase inhibitor, which is a therapeutic agent for hyperuricemia, or intermediates of the same, said method being efficient and using a short process. The present invention is a novel coupling method for obtaining a compound represented by formula (3) by bringing about a coupling reaction between a compound represented by formula (1) and a compound represented by formula (2), in the presence of a palladium compound, a ligand capable of coordinating to the palladium compound, a base, a C1-C40 carboxylic acid, and at least one kind of additive.

supporting information, p. 7677 - 7683 (2012/11/06)

The copper(II)-catalyzed dehydrogenative coupling between two different azoles for the preparation of unsymmetrical biazoles has been developed. The current catalytic system can effectively control the chemoselectivity for heterocoupling over homocoupling.

PROCESS FOR PRODUCING PHENYL-SUBSTITUTED HETEROCYCLIC DERIVATIVE THROUGH COUPLING USING TRANSITION METAL CATALYST

-

Page/Page column 24, (2012/01/13)

A process for efficiently producing, through few steps either a xanthine oxidase inhibitor, which is a therapeutic agent for hyperuricemia, or an intermediate therefore. The process is a novel coupling process which comprises subjecting a compound represented by formula (1) to coupling reaction with a compound represented by formula (2) in the presence of a transition metal compound to thereby obtain a compound represented by formula (3).
