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

Open PHACTS is an Innovative Medicines Initiative (IMI) project, aiming to reduce the barriers to
drug discovery in industry, academia and for small
businesses.
Semantic web is one of the corner stones

What does e-Science do in
?ChemSpider provides many of the physicochemical properties within the Open PHACTS Discovery Platform
e-Science develop tools to check and standardise chemical structures
