Thionyl Chloride → 3-Cyclopentyl-2-phenylpropionyl chloride

Participants

Reaction Steps

To the title B compound, 3-cyclopentyl-2-phenylpropionic acid (3.1 g, 14.2 mmol) is added 10 mL of thionyl chloride and one drop of DMF. The reaction mixture is stirred at ambient temperature for 2 h. The excess thionyl chloride is evaporated and the residue is twice treated with toluene and evaporated to yield 3-cyclopentyl-2-phenylpropionyl chloride as an orange-yellow oil which is selected as such without further purification.
