Reaktionsschritte

Anhydrous K2CO3 (18.43 g, 0.13 mol) was added to 300 mL of CH3CN, and the solution was degassed with N2 for 20 minutes. Methyl-4-hydroxybenzoate (6.27 g, 41.2 mmol) was added to the reaction flask, which was heated to 70° C., following which 1-bromodecane (8.8 mL, 42.5 mmol) was added. The above solution was refluxed for 12 hours, and upon cooling the solvent was removed under reduced pressure. The residue was taken in CH2Cl2 (200 mL) and washed with 1 M HCl (100 mL). The organic layer was washed with distilled H2O (100 mL), and the solvent was removed under reduced pressure. Yield 12.0 g (quant.). 1H NMR: δH (CDCl3; 300 MHz): 0.90 (3
