  • Patent number: 7947667
    Abstract: A process for preparing an intermediate compound of formula (II) where X is as defined in the specification, R1 is haloalkyl, alkyl, alkenyl, cycloalkyl, carboxyalkyl, alkoxycarbonylalkyl, aryl or arylalkyl; R2, R3, R4 and R5 are organic groups as defined in the specification, which process comprises aromatisation of a compound of formula (III) where R1, R2, R3, n, X and R5 are as defined in relation to formula (II) and R4? is a group R4 or a precursor group thereof, and thereafter if necessary or desired, carrying out one or more of the following steps: (i) removing any hydroxy-protecting groups R; (ii) converting a precursor group R4? to a group R4, or where R4? is a group R4, converting it to a different such group. Compounds obtained are useful intermediates for example in the preparation of fulvestrant. Novel intermediates are also claimed.

  • Publication number: 20060261651
    Abstract: A car seat has a support base configured to test on a dedicated seat of a vehicle when installed. The car seat also has a seat shell coupled to the support base that defines a seating surface of the car seat. The seating surface has a seat bottom portion that terminates at a front end of the seat shell. The seat shell is adjustable to a plurality of selectable seat recline orientations relative to the support base. A recline lever is mounted under the seat shell and is movable between a latch position and a release position. A handle on one end of the recline lever is positioned below and projects forward of the front end of the seat shell. The handle is movable upward to move the recline lever to the release position. A shroud projects forward from the front end of the seat shell and is positioned above and spaced from the handle. A top side of the shroud is positioned to act as a fixed bearing surface for grasping and moving the handle upward toward the shroud.
