Claim 4:
5. The method according to claim 1, wherein 2,3-dimethylanisole, copper sulfate pentahydrate and potassium persulfate, as starting materials, are stirred in a mixed solvent of acetonitrile and water to prepare 2-methoxy-6-methylbenzaldehyde; aluminum trichloride is added to a dimethoxymethane solution of 2-methoxy-6-methylbenzaldehyde, and stirred at room temperature overnight to obtain 2-hydroxy-6-methylbenzaldehyde; 2-hydroxy-6-methylbenzaldehyde and bromopropanol are added into a solution of potassium carbonate in N,N-dimethylformamide at 90° C. overnight, after a reaction is completed, insoluble matter is removed by filtration, and HCl is added to a filtrate to obtain 2-(3-hydroxypropoxy)-6-methylbenzaldehyde; 2-(3-hydroxypropoxy)-6-methylbenzaldehyde and 4-cyano-4-(thioben-zoylthio) valeric acid are dissolved in dichloromethane, a solution of N,N′-dicyclohexylcarbimide and 4-dimethylaminopyridine in dichloromethane is added dropwise, and a resulting reaction mixture is stirred at room temperature for 24 hours to obtain the RAFT reagent.
