Participants

Reaction Steps

A solution of (+/-)-3-(3-cyclopentyloxy-4-methoxyphenyl)-3-phenylethynylpropionic acid chloride (150 mg, 0.42 mmol) and dimethylaniline (100 mg, 0.83 mmol) in Et2O (5 ml) was treated with i-propanol (1 ml) and stirred at 23° for 18 hr. The solvents were evaporated, and the residue taken up in Et2O, washed with 3N HCl, H2O, dried, and the solvent evaporated. The residue was purified by flash chromatography (silica gel, 20% EtOAc/hexane), and gave the titled compound, 82 mg (54%).
