| titleOfInvention | PROCEDURE FOR OBTAINING BUTYROPHENONE DERIVATIVES. |
| abstract | Process for obtaining derivatives of butyrophenone, of formula i, ** (see formula) ** Wherein r1 is hydrogen, alkyl of 1 to 3 carbon atoms, fluorine, chlorine, bromine or methoxy, R2 is hydrogen, alkyl of 1 to 3 carbon atoms, chloro or methoxy, or R1 and r2 are in the ortho position to one another and together form a methylenedioxy group, R3 is hydroxy, alkylcarboxy of 2 to 5 carbon atoms or monoalkylcarbamoyloxy of 2 to 5 carbon atoms, and A is carbonyl, 1,3-dioxolan-2-ylidene or 1,3-dioxan-2-ylidene, Characterized in that a compound of formula ii is reacted, ** (see formula) ** Wherein r1, r2 and r3 have the meanings indicated above, with a compound of formula iii, ** (see formula) ** Wherein x is chlorine, bromine, iodine or an organic sulphonic acid radical, and a has the meaning indicated above, and if it is carbonyl, it can be protected by ketal, thioxo or thioketal formation and, if necessary, separate any carbonyl protecting groups from the resulting compound.
