| titleOfInvention | PROCEDURE FOR OBTAINING DERIVATIVES OF 3-HYDROXIF-TALIMIDINA. |
| abstract | Procedure for obtaining 3-hydroxyphthalimidine derivatives, of formula I, **(See formula)** wherein each of R and R1 which may be the same or different, signifies a hydrogen, chlorine or fluorine atom, and R2 signifies an alkyl radical of 1 to 5 carbon atoms, or a radical of formula III, **(See formula)** wherein each of R3 and R4, which may be the same or different, means a hydrogen, chlorine, or bromine atom, or a straight-chain alkyl radical containing 1 to 3 carbon atoms, with the proviso that when each one of R3 and R4 has a meaning other than a hydrogen atom, at least one of R3 and R4 is in a position other than an ortho position of the phenyl ring, characterized in that a compound of formula IV is reacted, **(See formula)** where R and R1 have the meanings indicated above, and X means a chlorine or bromine atom, with a compound of formula V, H2NCH2CH2NHSO2R2 V wherein R2 has the meaning indicated above, in an organic solvent that is inert under the reaction conditions, preferably at a temperature of from about 20º to about 60ºC, more preferably from 40º to 50ºC.
