Abstract: There is provided a new and improved synthetic route for the synthesis of the compound 1-{2-[(1R)-1-aminoethyl]-4-chlorobenzyl}-2-thioxo-1,2,3,5-tetrahydro-4H-pyrrolo[3,2-d]pyrimidin-4-one (Formula (I)) that is readily scalable for commercial production. Also provided are important intermediate compounds that are formed in the new and improved synthetic route for the synthesis of the compound of formula (I).

Abstract: A downhole induction resistivity assembly that comprises a downhole tool string component. The tool string component comprises an induction transmitter. The transmitter is adapted to induce an induction field in the surrounding formation. A first induction receiver is spaced apart from the transmitter and is adapted to measure the induction field. A magnetic field generating mechanism is disposed adjacent on either or both sides of the transmitter and adapted to guide the transmitter's signal into the formation. A second induction receiver is disposed in close proximity to the magnetic field generating mechanism and is adapted to measure the magnetic field generated by the mechanism.

Abstract: A downhole drill string component is disclosed comprising a substantially cylindrical cage with a hollow bore. An inner diameter of the cage is slideably connectable to a mandrel. A stab connection originates from one end of the cage and a plurality of downhole drill string instruments is circumferentially disposed around an outer diameter of the cage.
