Reaction Steps

In a 1 liter 2-neck roundbottom flask, 40 grams of 4-aminobenzoic acid was dissolved in about 400 mL of dioxane. Then, 19.35 g of cyclopentanecarbonyl chloride was added dropwise to the solution. The reaction intermediate, 4-(cyclopentanecarbonyl-amino)-benzoic acid, formed as a white solid in the step and was collected by filtration. After washing the product with about 200 mL dioxane and then with about 1 liter of boiling water, the reaction intermediate was dried in an oven at 110° C. The yield at this step was about 27.7 g (81%).
