Abstract: The present invention relates to a method comprising the step of contacting a protected N,N-bis(2-X-ethyl)amine with a (2-fluorophenyl)acetonitrile in the presence of a water-soluble phase transfer reagent, concentrated aqueous base, and an immiscible organic solvent, and under such conditions to form a 4-(2-fluorophenyl)-4-piperidinecarbonitrile in at least a 70% yield, wherein X is a leaving group. The 4-(2-fluorophenyl)-4-piperidinecarbonitrile is useful in preparing spiroindolines, which can be used as precursors of compounds that are modulators of CCR2 receptor.

Abstract: The present invention provides a method and kit for detection of two or more target molecules in a single tissue sample, such as for gene and protein dual detection in a single tissue sample. Methods comprise treating a tissue sample with a first binding moiety that specifically binds a first target molecule. Methods further comprise treating the tissue sample with a solution containing a soluble electron-rich aromatic compound prior to or concomitantly with contacting the tissue sample with a hapten-labeled binding moiety and detecting a second target molecule. In one example, the first target molecule is a protein and the second is a nucleic acid sequence, the first target molecule being detected by immunohistochemistry and the second by in situ hybridization. The disclosed method reduces background due to non-specific binding of the hapten-labeled specific binding moiety to an insoluble electron rich compound deposited near the first target molecule.

Methods of carbon restoration in a material are also described that include: a) providing a carbon-deficient material having a plurality of reactive silanol groups; b) providing at least one reactive surface modification agent; and c)chemically capping at least some of the plurality of reactive silanol groups with the at least one of the reactive surface modification agents.

Abstract: Systems for towing a trailer by a towing vehicle and a method for controlling such a system are disclosed. The systems and method are configured to maintain a constant towing load on the towing vehicle as well as optimizing other performance criteria such as fuel efficiency. The system comprises a closed loop controller, a towing arm assembly, a load measuring device, an electric hub motor, brakes, a motor controller and a brake controller disposed on the trailer. In another embodiment, two separate systems are installed, one on each side of the trailer. A load force feeds into a PID controller programmed with preset proportional, differential and integral parameters. The PID controller generates a command signal to either modulate the brakes or motor up or down depending on the sign of the command signal. A process output updates the system which continuously adjusts based on driving conditions.
