Water → 4-Ethyl-3-(3-hydroxy-propoxy)-benzoic acid methyl ester

Participants

Reaction Steps

To a solution of 4-ethyl-3-hydroxy-benzoic acid methyl ester (3.21 g, 17.81 mmol) in acetonitrile (35 mL) are added 3-bromo-1-propanol (1.85 mL, 21.37 mmol) and K2CO3 (3.69 g, 26.7 mmol). The solution is refluxed for 4 h, then poured into water and extracted three times with AcOEt. The combined organic extracts are washed with brine, dried over Na2SO4, filtered and concentrated to give the title product. TLC, Rf (c-hexane/AcOEt 8:2)=0.15, MS (LC-MS): 239.2 [M+H]+, tR (HPLC, Macherey-Nagel Nucleosil C18 column, 10-100% CH3CN/H2O/5 min, 100% CH3CN/3 min, flow: 1.5 ml/min): 5.10 min.
