| titleOfInvention | PROCEDURE TO PREPARE PIPERACIN DERIVATIVES. |
| abstract | Process for preparing piperazine derivatives, of formula I, in which R1 and R4 are identical or different and each signifies hydrogen, halogen with an atomic number of 9 to 35, or an alkyl or alkoxy group with 1 to 4 carbon atoms, each of R2 and R3 means hydrogen, or R2 and R3 together form an oxygen atom, B and D together with the carbon atoms to which they are attached, form a benzene ring, or B means sulfur, and B and D together with the carbon atoms to which they are attached, they form a thiophene ring that can optionally be substituted in an alpha position relative to the sulfur atom by halogen with atomic number 9 to 35 or alkyl with 1 to 4 carbon atoms, and when B and D together with the carbon atoms, to which they are attached, form a benzene ring. |
