  • Patent number: 9499507
    Abstract: The invention relates to a method for preparing 5-amino-benzoyl-benzofuran derivatives having the general formula in which R1 is hydrogen or an alkyl or aryl group and R2 is hydrogen, an alkyl, alkoxy or dialkylaminoalkoxy group. According to the invention, the compounds having formula I are prepared by hydrogenating a 5-nitro-benzofuran derivative having the general formula in which R1 and R2 have the same meaning as above in the presence of palladized charcoal as a catalyst and in an ether or a mixture of ether as a solvent, thus forming the desired compounds.
    Type: Grant

  • Patent number: 8748636
    Abstract: The disclosure relates to a process for preparing benzofuran derivatives of general formula I: in which R, R1, and R2 are as defined in the disclosure; by coupling the hydroxylamine with a diketone of general formula III: in order to form an oxime that is then cyclized by heating in order to form the desired compound.

  • Patent number: 8686180
    Abstract: This disclosure relates to a process for preparing 5-aminobenzofuran derivatives of general formula (I): in which R1 and R2 are as defined in the description, by treating a 5-N-alkylamidobenzofuran derivative of general formula (II): in which R1, R2, and R3 are as defined in the description, with a strong acid, so as to form an acid addition salt of the compound of formula (I), which salt is itself treated, if necessary, with a basic agent so as to form this compound of formula (I) in free base form.

  • Patent number: 7218233
    Abstract: An identity booklet such as a passport including a reinforced paper cover made up of a top cover board (16) and bottom cover board (14), an inside quire whose top (22) and bottom (20) flyleaves are laminated respectively at the back of the top cover board and in front of the bottom cover board and a radio frequency identification device (RFTD) made up of a chip (12) and an antenna connected to the terminals of the chip. The antenna includes a first part of the antenna (10) placed on the surface of the top and/or bottom cover board designed to be laminated with the corresponding flyleaf and a second part of the antenna placed on the surface of the top and/or bottom flyleaf designed to be laminated with the corresponding cover board, the first and second parts of the antenna being connected to constitute the antenna when the flyleaves are laminated with the cover boards.
