Key intermediate for synthesizing 1-alkyl-2-trifluoromethyl-5-amino-1H-imidazole, and preparation method thereof

The invention discloses a key intermediate for synthesizing 1-alkyl-2-trifluoromethyl-5-amino-1H-imidazole, and a preparation method thereof. A purpose of the invention is mainly to solve the technical problem of lack of a 1-alkyl-2-trifluoromethyl-5-amino-1H-imidazole synthesis process in the prior art. The method comprises the following steps: carrying out alkylation on a compound II (2-trifluoromethylbenzimidazole) as a raw material to generate a compound III; opening a benzene ring through oxidizing to obtain a diacid compound IV; esterifying the compound IV to generate a compound V; carrying out monohydrolysis to obtain a compound VI; carrying out cutius rearrangement on the compound VI to generate a compound VII; hydrolyzing the ester group of the compound VII to generate a compoundVIII; and finally carrying out decarboxylation and tert-butyloxycarbonyl removal to obtain the compound I (1-alkyl-2-trifluoromethyl-5-amino-1H-imidazole).

FLUOROALKYLATING AGENT

Problem to be Solved It is intended to provide an industrially preferable fluoroalkylating agent and use thereof. Solution The present invention provides a fluoroalkylating agent represented by the general formula (1) wherein R1 is a C1 to C8 fluoroalkyl group; R2 and R3 are each independently a C1 to C12 alkyl group or the like; Y1 to Y4 are each independently a hydrogen atom, a halogen atom, or the like; and X? is a monovalent anion. A compound of the general formula (3): R4—S—R1 having an introduced C1 to C8 fluoroalkyl group is easily obtained by reacting a compound of the general formula (2): R4—S—Z wherein R4 is a hydrocarbon group or the like; and Z is a leaving group, with the compound of the general formula (1).

A method for synthesizing three fluoromethylation aromatic hydrocarbon

The invention provides a synthetic method for a trifluoromethyl methylation arene. The trifluoromethyl methylation arene is prepared by reacting a halogenated arene, copper powder, elemental iodine and trifluoroacetic anhydride in an organic solvent under an inert atmosphere protection state. The method has the advantages of being simple and efficient, cheap in raw materials, low in synthetic cost, high in universality and repeatability, and the like, and can be popularized and applied to the fields of the synthesis of trifluoromethyl methylation aromatic derivatives.
