Abstract
"METHOD OF PREPARATION OF NEW CHROMOGENIC COMPOUNDS" characterized in that a mixture of 9.26 gr. (0.03 gram molecules) of 1-ethyl-2-methyl- is heated in a steam bath for two and a half hours. 3- (2-carboxybenzoyl) indole, 6.63 gr. of (0.03 gram molecules) of 1-benzyl-2-methylindole and 90 ml of acetic anhydride, the reaction mixture is poured into ice water and made basic with ammonium hydroxide to a pH of 8-9, it is necessary For further cooling, the aqueous solution is extracted with benzene, washed three times with a 5% aqueous sodium hydroxide solution and with water afterwards until completely neutral.
