  The value of the invention is the application of the cyclization of Schiff-bases of the general formula (3a-i), where R1 - R8 are substituents defined in example 1, whereby R9 = Cl using complex bases of amides of group I of the periodic table (NaNH2, KNH2) from 2.1 - 5 equiv. and alcoholates of group I of the periodic table (t-BuONa, tBuOK) from 0.05 - 2 equiv. with the advantage of application of 3 equiv. of NaNH2 and 0.05 equiv. of t-BuONa, or their mixtures with PEG (m.w. = 500 - 6000), or crown ethers, or catalysts of phase transfer lithium in inert proton-free diluents, such as benzene, cyclohexane, toluene, xylene, 1,2-dimethoxyethane, dioxane, etc., with the advantage of using THF, at a temperature from 20 °C to boiling point of the diluent used, or with the application of organo-metallic bases such as LDA, t-BuLi in inert proton-free diluents at a temperature from -80°C to 25 °C.

  The methylation of 2-formyl-3-hydroxyindole was studied, and the sequence of introduction the methyl groups was traced by1H NMR spectroscopy. The O-methyl, N-methyl, and N,O-methyl derivatives of 2-formylindole, and also the O-methyl and N-methyl derivatives of 2-methyl-3-ethoxycarbonyl-4-hydroxypyrrole were synthesized. Novel derivatives of indolyl- and pyrrolylacrylic acids were obtained on the basis
