The present invention provides novel heteroaryl compounds, pharmaceutical acceptable salts and formulations thereof. They are useful in preventing, managing, treating or lessening the severity of a protein kinase-mediated disease. The invention also provides pharmaceutically acceptable compositions comprising such compounds and methods of using the compositions in the treatment of protein kinase-mediated disease.
Alkylisocyanates are prepared by reacting a phenol or substituted phenol and phosgene in a halogenated hydrocarbon solvent with aqueous alkali metal hydroxide to produce a corresponding chloroformate, reacting the resulting chloroformate solution with aqueous alkylamine to give a corresponding N-alkylcarbamate which, after solvent is stripped, is then pyrolyzed to yield the alkyl isocyanate. Solvent and the starting phenol may be recovered and recycled to the process.

A preparation of aryl carbamates can be achieved readily by carbonylation of an aromatic polyamine compound with diphenyl carbonate (DPC) using a combination of an organic acid and a tertiary amine as a catalyst. Aryl carbamate can be converted into 4,4′-diphenylmethane diisocyanate (MDI) by heating it at about 200 to about 230° C. in a non-polar solvent containing inhibitor such as benzoyl chloride. In another application, trans-ureation of biscarbamates with an amine or mixed amines is found to be extremely facile in a polar solvent such as dimethyl sulfoxide (DMSO) and tetramethylene sulfone (TMS) in absence of any catalyst to make polyurea polymers of high molecular weights. Thus, efficient green-chemistry processes based on biscarbamates in making isocyanate products as well as urea prepolymers, urea elastomers and urea plastics have been developed in all in excellent yields without using reactive phosgene or 4,4′-diphenylmethane diisocyanate separately in the trans-ureation polymerizations.
A novel and simple approach to the synthesis of sulfonylureas has been reported. It involved the reaction of various amines with diphenyl carbonate to yield the corresponding carbamates, which subsequently reacted with different sulphonamides to produce different sulfonylureas in excellent yields. The first reaction of diphenyl carbonate with amines was carried out in aqueous:organic (H2O:THF, 90:10)
已经报道了一种新颖且简单的合成磺酰脲类的方法。它涉及各种胺与碳酸二苯酯的反应,以产生相应的氨基甲酸酯,其随后与不同的磺酰胺反应,以优异的产率产生不同的磺酰脲类。碳酸二苯酯与胺的第一反应是在室温下于水性:有机(H 2 O :THF,90 : 10)介质中进行的,以生成氨基甲酸酯,该氨基甲酸酯与磺酰胺反应后,直接通向磺酰脲类。上述方法避免了传统的多步骤方案,并且避免使用有害,刺激性,有毒和对水分敏感的试剂,例如光气,异氰酸酯和/或氯甲酸酯。
