Reaktionsschritte
In a four-neck flask having an inner volume of 100 ml, 4.86 g (25 m.mols) of (2,4-dimethyl-3-pentyl) methanesulfonate, 5.36 g (25 m.mols) of 3-phenylsalicylic acid, 2.65 g (25 m.mols) of sodium carbonate, and 50 ml of dimethyl formamide were placed and left reacting at 90° C. for three hours. After the reaction, the reaction mass was thrown into 100 ml of ice water and extracted twice with 150 ml of ethyl acetate. The organic layer obtained consequently was washed twice with 50 ml of water. Then, by distilling the organic layer thereby expelling the solvent by evaporation, 5.00 g (16 m.mols) of 2-(2,4-dimethyl-3-pentyloxy)carbonyl-6-phenylphenol was obtained as the product aimed at.
