The document discusses the Royal Society of Chemistry's (RSC) efforts to reflect changes in the digital world through its e-Science initiatives and global chemistry network. It summarizes RSC's work on knowledgebases like ChemSpider, which contains over 29 million chemicals and reactions. It also discusses challenges of big data, text mining, crowdsourcing data quality, and developing new interfaces to improve access and navigation of chemical information online. The goal is to build a global network to share standardized chemistry data and tools to advance science.

33. DERA and Text Mining
The N-(β-hydroxyethyl)-N-methyl-N'-(2-trifluoromethyl-1,3,4-
thiadiazol-5-yl)urea prepared in Example 6, thionyl chloride ( 5
ml ) and benzene ( 50 ml ) were charged into a glass reaction
vessel equipped with a mechanical stirrer, thermometer and
reflux condenser .
The reaction mixture was heated at reflux with stirring, for a
period of about one-half hour .
After this time the benzene and unreacted thionyl chloride
were stripped from the reaction mixture under reduced
pressure to yield the desired product N-(β-chloroethyl)-N-
methyl-N'-(2-trifluoromethyl-1,3,4-thiaidazol-5-yl)urea as a solid
residue

aiming to reduce the barriers to
drug discovery in industry,
academia and for small
businesses.
Semantic web is one of the
corner stones
