The present invention is directed to a method for the synthesis of a bi-functional complex comprising a molecule part and an identifier oligonucleotide part identifying the molecule part. A part of the synthesis method according to the present invention is preferably conducted in one or more organic solvents when a nascent bi-functional complex comprising an optionally protected tag or oligonucleotide identifier is linked to a solid support, and another part of the synthesis method is preferably conducted under conditions suitable for enzymatic addition of an oligonucleotide tag to a nascent bi-functional complex in solution.

Phenyl isothiocyanate reacts with ethyl γ-chloroacetoacetate in the presence of sodium hydride to give ethyl 2-anilino-4-oxo-4,5-dihydrothiophen-3-carboxylate (1b). The compound (1b) shows typical reactions of a keto methylene compound; the Vilsmeier reagent and phosphorus oxychloride give the chloroformylthiophen (10). A possible sulphine derivative (11) is obtained from (1b) with thionyl chloride
