THIAZOLIDEN-2,4-DIONE DERIVATIVE, PROCESS FOR PREPARATION THEREOF, THIAZOLIDIN-2,4-DIONE DERIVATIVE AS INTERMEDIATE PRODUCT WHEN PREPARING AROMATIC AMINOALCOHOL DERIVATIVES

摘要

FIELD: chemistry of aromatic aminoalcohol derivatives as intermediate compounds. SUBSTANCE: product: thiazplidine-2,4- -dione of formula , where R⁷ is hydrogen or acetyl. Compound is prepared by reacting n-hydroxybenzaldehyde with thiazolidin-2,4-dione. Resulting 5-(4-acetoxybenzilidene)- -thiazolidin-2,4-dione is hydrogeneted to 5-(4-acetoxybelzyl) thiazolidin-2,4-dione which is reacted with triphenylmethyl chloride and converted into desired compound. EFFECT: higher efficiency. 6 cl
