実験手順
To the solution of 3-(4-bromophenyl)butan-1-ol (791 mg, 3.47 mmol) in dichloromethane (50 mL) was added 3,4-dihydro-2H-pyran (437 mg, 5.2 mmol) and p-toluenesulfonic acid (60 mg, 0.347 m mol), the solution was stirred for 12 hours at room temperature, then the solution was washed with water and dried with sodium sulfate, concentrated to give 2-(3-(4-bromophenyl)butoxy)-tetrahydro-2H-pyran (1.05 g, 97%).
