FIELD: chemistry.
SUBSTANCE: disclosed is a group of inventions relating to methods of producing synthetic bilirubin. Method for synthesis of bilirubin involves dimerisation of a compound of formula 6 and replacing X in the product with -C(=O)H to obtain a compound of formula 1, obtaining a compound of formula 3 by combining a compound of formula 1 with compound of formula 2 in the presence of a base and a solvent and obtaining bilirubin from the compound of formula 3. Substitutes R1-R5 and X are described in the claim.
EFFECT: providing a method for synthesis of the desired compound.
