preparation example 1
[0275] 92 grams of thioglycolic acid (thioglycolic acid) (Sigma Aldrich Co., Ltd. (SigmaAldrich Co., Ltd.)), 400 grams of polyoxyethylene monomethyl ether (polyoxyethylene monomethyl ether) (Hannong Chemicals Inc.)), 20 grams of p-toluenesulfonic acid monohydrate (Sigma Aldrich Ltd.) and 500 milliliters of cyclohexane were put together, and then when the mixture was heated under nitrogen atmosphere so that the cyclohexane could be refluxed, The water generated therein was removed by using a dean stark apparatus. When no more water was produced, the reactant was cooled to room temperature and then washed by using ethyl acetate and distilled water. The organic layer was neutralized by using NaOH diluent. Subsequently, the neutralized resultant was washed several times by using distilled water, by using MgSO 4 Treated to dry moisture, and then concentrated under reduced pressure to finally obtain the compound represented by Chemical Formula 1-1.

preparation example 2
[0285] 92 g of thioglycolic acid (Sigma-Aldrich Ltd.), 206 g of tripropylene glycol monomethyl ether (mixture of isomers, Tokyo Chemical Industry Co., Ltd. (TCI)), 10 g of p-toluenesulfonic acid monohydrate ( Sigma Aldrich Co., Ltd.) and 500 ml of cyclohexane were put together, and then the water produced therein was removed by using a Dean Stark apparatus while heating the mixture under a nitrogen atmosphere so that the cyclohexane could be refluxed. When no more water was produced, the reaction was cooled to room temperature and then washed by using ethyl acetate and excess distilled water. The organic layer was neutralized by using NaOH diluent. Subsequently, the neutralized resultant was washed several times by using distilled water, by using MgSO 4 Treated to dry moisture, and then concentrated under reduced pressure to finally obtain the compound (ligand) represented by Chemical Formula 1-2.
