Procedure:
Synthesis of monomers was achieved from 3,5-dihydroxybenzoic acid or 3,5-dihydroxybenzyl alcohol as shown in above scheme. Commercially available 3,5-dihydroxybenzoic acid 1 was dissolved in ethanol along with catalytic amount of concentrated sulfuric acid and refluxed for 12 h to obtain ethyl-3,5-dihydroxybenzoate 1a. The ester 1a was then treated with one equivalent of alkyl halide to afford the mono alkylated ester 3 and 4. The yield of this reaction was rather low, because of the disubstituted byproduct obtained in the reaction along with the product as a statistical mixture. Compounds 3 and 4 were then reduced using LiAlH4 in dry THF under ambient temperature to give the monoalkylated phenols 3a and 4a. Compounds 2a and 5a were prepared by the reaction of 3,5-dihydroxybenzyl alcohol with 1 equivalent of alkyl halide under alkylation conditions. The phenols 2a-5a were then treated with tert-butylbromoacetate and sodium iodide to give compounds 2b-5b, which upon oxidation by PCC afforded the corresponding aldehydes 2c-5c. Treatment of aldehydes with methyl triphenylphosphonium bromide and potassium tert-butoxide under THF afforded the monomers 2d-5d. Polymers 2e-5e (n>1) was synthesized by nitroxide mediated living polymerization, using unimolecular intiator. The polymers were then hydrolyzed using potassium hydroxide as the base to afford carboxylic acid polymers 2f-5f.

The resulting dark brown oil was crystallized from pet ether to give 7.3 g (87%) of 8-Amino-6-methoxy-4-methyl-5-(5-phenylpentoxy)quinoline as yellow green crystals, mp 65°-66° C. This material was used without further purification.

Procedure:
In 12.5 ml of dichloromethane, 4.4 g (20 mmol) of 5-(1-hydroxybutyl)-3-phenylisoxazole were dissolved. While the solution was being stirred, 35.2 g (60 mmol) of a 12.7% aqueous solution of sodium hypochlorite were added dropwise to the solution. Next, a liquid mixture which had been obtained by adding 0.48 g (6.1 mmol) of pyridine to 1.0 ml of 6N hydrochloric acid) was added dropwise over 1 hour and the reaction temperature was maintained at 20° C. After completion of the reaction, the organic layer was collected and was washed successively with a 5% aqueous solution of sodium hydrogensulfite, water and 1N hydrochloric acid. The organic layer was dried over anhydrous sodium sulfate and the solvent was distilled off under reduced pressure. The residue was then recrystallized from ethanol, whereby the target compound, namely, 5-butyryl-3-phenylisoxazole was obtained as crystals.
