2-(2-BROMOETHOXY)TETRAHYDRO-2H-PYRAN Chemical Properties,Usage,Production

Chemical Properties

Clear pale yellow liquid

Uses

2-(2-Bromoethoxy)tetrahydro-2H-pyran may be used in the synthesis of:

  • 4-(2-chloroethoxy)benzenesulfonyl chloride
  • estrogen ligands bearing carborane
  • 2-(2-(1,3-di((E)-2-(2-(2-(2-(5-(4-(tert-butoxycarbonyl(methyl)amino)styryl)pyridin-2-yloxy)ethoxy)ethoxy)ethoxy)ethoxy)propan-2-yloxy)ethoxy)-tetrahydro-2H-pyran

General Description

2-(2-Bromoethoxy)tetrahydro-2H-pyran is an organic building block. It has been synthesized by employing 2-bromoethanol as a starting reagent.

Synthesis

110-87-2

540-51-2

17739-45-6

To a mixed solution of 2-bromoethanol (3.8 g, 30.0 mmol) and 3,4-dihydro-2H-pyran (2.5 g, 30.0 mmol) dissolved in dichloromethane (50 mL), p-toluenesulfonic acid (380.0 mg, 2.2 mmol) was added in portions. The reaction mixture was stirred at room temperature for 2 hours. After completion of the reaction, the mixture was concentrated and purified by silica gel column chromatography (petroleum ether/ethyl acetate, 50:1) to afford 2-(2-bromoethoxy)tetrahydro-2H-pyran (5.6 g, yield: 89%) as a colorless oil.
