e) for detecting indium(III) was synthesized. Sensor BHC can detect In(III) by a fluorescence turn-on method. The detection limit was analyzed to be 0.89 μM. Importantly, this value is the lowest among those previously known for fluorescent turn-on In(III) chemosensors. Based on the analytical methods like ESI-mass, Job plot, and theoretical calculations, the detection mechanism for In(III) was illustrated

CE-178,253 benzenesulfonate (1) is a CB1 antagonist discovered by Pfizer medicinal chemists. Two syntheses Of this compound are described. The first, based on the discovery synthesis, involves assembly of an aryl-substituted pyrazolotriazine core onto which the second aryl moiety is installed by a Suzuki Coupling: this route has been scaled to provide up to 6 kg of API. A second. more convergent route is also described, which installs the pyrazolotriazine containing both aryl substituents by condensation of a bromoketone with a substituted thiosemicarbazide. This route has been demonstrated on laboratory scale and is viewed as the preferred bond-forming sequence. (C) 2008 Elsevier Ltd. All rights reserved.
