Multiplex synthesis method of compound library and parallel synthesizer of compound library using same

A parallel synthesizer of a compound library, comprising:

• a first inlet unit through which a first reactant is introduced and at least one inlet is formed;
• a flow distributor connected to the first inlet unit and distributing the introduced first reactant in equal amounts, and formed with a damper and a baffle;
• a plurality of ducts connected to the flow distributor and through which the distributed first reactant passes, respectively;
• a second inlet unit located at one side of the ducts and formed with an inlet through which a second reactant is introduced;
• a plurality of reactors respectively connected to the ducts and in which a product is generated by a chemical reaction of the first reactant and the second reactant transported through the ducts;
• and
• a discharge unit formed on one side of the reactors to discharge the product,
• wherein the temperature and time of the chemical reaction can be independently controlled in each of the reactors,
• wherein each of the ducts is a coiled capillary thinner than the connected reactors,
• wherein a flow velocity in the ducts is 0.3 to 0.5 mL/min,
• wherein the first reactant is an aryldiazonium salt, and
• wherein the aryldiazonium salt comprises a cation represented by Chemical Formula 1 below:
• In Chemical Formula 1 above, R is hydrogen, a hydroxyl group, an ether group, a halogen atom, a carbonyl group, a nitro group, a naphthyl group, a cyano group, an amino group, an amidino group, hydrazine, hydrazone, a carboxyl group, a sulfonic acid group, a phosphoric acid group, an alkyl group having 1 to 12 carbon atoms, an alkenyl group having 1 to 12 carbon atoms, an alkynyl group having 1 to 12 carbon atoms, an aryl group having 6 to 10 carbon atoms, or an arylalkyl group having 7 to 10 carbon atoms.
