-
Paragraph 0246; 0252; 0787-0790, (2019/07/03)
The present invention relates to fused heterocyclic derivatives, processes for their preparation and their use in medicine. Specifically, the present invention relates to a novel derivative represented by the formula (I′), or its pharmaceutically acceptable salt thereof, a pharmaceutical composition containing the derivative or its pharmaceutically acceptable salt thereof, and the method for preparing the derivative and its pharmaceutically acceptable salt thereof. The present invention also relates to the use of the derivative and its pharmaceutically acceptable salt thereof, or a pharmaceutical composition containing the derivative and its pharmaceutically acceptable salt thereof in the preparation of medicines, in particularly as IDO inhibitor medicines, for treating and/or preventing cancers. Wherein each substituent of the formula (I′) is the same as defined in the specification.
Pyrazole N-alkylation method
-
Paragraph 0037; 0038, (2018/12/14)
The invention provides a pyrazole N-alkylation method. Pyrazole or pyrazole derivatives and alkyl halogenated hydrocarbons react in a solvent under the existence of quaternary ammonium salt catalysts;N-alkyl substituted pyrazole is obtained. The method provided by the invention has the advantages that the operation is simple; the cost is low; the anhydrous oxygen-free environment is not needed; heating is not needed; the yield is high; the amplified industrialized production can be easily realized.

, p. 931 - 939 (2007/10/03)
Starting from 1H-pyrazol, a wide number of 1-alkyl-1H-pyrazol-4-yl and 1-alkyl-1H-pyrazol-5-ylboronic acids and their pinacol esters were synthesized and characterized. The key step in the described methodology is the regioselective lithiation of the pyrazole ring. The synthesized pinacolates are stable under prolonged storage and can be used as convenient reagents in organic synthesis.
