반응 단계

2-Bromo-1-ethanol (5.0 g, 0.04 mol) and 4-(trans-4-propylcyclohexyl)phenol (4.4 g, 0.02 mol) were dissolved in ethanol (300 ml) and agitated at room temperature. To this solution was gradually dropwise added a solution of KOH (10 g) in water (20 ml), over 30 minutes, followed by stirring for 40 hours, distilling off about 200 ml of ethanol under reduced pressure, adding water (500 ml) to deposit solids, separating the solids from liquid, dissolving them in toluene (100 ml), filtering off insoluble matter, washing the toluene solution twice with 2N-NaOH, then three times with water, drying over anhydrous sodium sulfate, distilling off toluene and recrystallizing the resulting crystals from n-heptane to obtain the objective 1-(2-hydroxyethoxy)-4-(trans-4-propylcyclohexyl)benzene. Yield: 1.8 g (34%). C-S: 71.5° C. S-I: 81.4° C.
