Paragraph 0810-0811, (2019/05/15)
The present invention relates to compounds of formula (I) that are useful as hepatitis C virus (HCV) NS5A inhibitors, the synthesis of such compounds, and the use of such compounds for inhibiting HCV NS5A activity, for treating or preventing HCV infections and for inhibiting HCV viral replication and/or viral production in a cell-based system.

Paragraph 0103-0105, (2018/09/13)
The invention relates to the field of organic synthesis, in particular to a preparation method of 3-aminophenylacetylene. The preparation method of 3-aminophenylacetylene comprises the following steps: preparing a compound shown as formula III from a compound shown as formula I and a compound shown as formula II through a coupling reaction; preparing a compound shown as formula V from the compoundshown as the formula III. The preparation method of 3-aminophenylacetylene is short in synthetic route, low in energy consumption and environmentally friendly, and the target product can be obtainedparticularly from 3-bromophenylacetylene as a raw material through two steps of reactions. Besides, prepared 3-aminophenylacetylene is used as a raw material of an anticancer drug, so that generationof potential genotoxic impurities containing halogen and ethylenic linkage structures can be avoided effectively from the source.

Paragraph 0040, (2018/06/04)
The invention provides a high-efficiency, high-selective synthesis of different substituted functional group containing organic amide compound, it adopts the cuprous iodide as a catalyst, in order to aryl diazonium tetrafluoroborate salts compounds and organic nitrile compound as the reaction substrate, the reaction system by adding the organic solvent, water and alkali. The advantage of this method: cheap and easily obtained catalyst; the substrate has a high applicability; mild reaction conditions, safe and reliable; the resulting target product selectivity is close to 100%, yield is as high as 90% or more. The method solves the traditional synthetic organic amide compound of rigorous reaction conditions, the reaction selectivity is poor, the experimental procedure is complicated, the productivity is low and needs to be used for the environment of a harmful reagent and the like, it has good industrial application prospect. The invention also provides a corresponding different substituted functional group containing organic amide compound. (by machine translation)

, p. 8282 - 8289 (2017/08/14)
The copper-catalyzed highly regioselective aminodifluoroalkylation of alkynes and α-bromodifluoroacetamides was realized for the first time. With this method, 3,3-difluoro-1H-pyrrol-2(3H)-ones were constructed in a single step from various alkynes and α-b
Selective N-acetylation of aromatic amines using acetonitrile as acylating agent
Saikia, Ujwal Pratim,Hussain, Farhaz L.,Suri, Mrinaly,Pahari, Pallab
supporting information, p. 1158 - 1160 (2016/03/09)
A method for N-acetylation of amines has been developed using acetonitrile as an acylating agent and in situ generated trimethylsilyl iodide as the catalyst under microwave heating condition. The reaction is selective toward aromatic amines while aliphatic amines remain intact. The process eliminates the requirement of toxic acylating reagents like acetic anhydride and acetyl chloride.
