Participants

Reaction Steps

0.21 g of 1,1′-carbonylbis-1H-imidazole was added to a solution of 0.19 g of 4-chlorobenzoic acid in tetrahydrofuran and stirred for 1 hour at room temperature. Then 5 ml of a solution of 0.25 g of 2-(i-propoxycarbonylamino)-3-phenylpropylamine in tetrahydrofuran was added to the above solution and stirred at room temperature for 4 hours. The reaction mixture was rinsed with water, the organic layer was dried over magnesium sulfate anhydrous, and the residual oily material obtained under a reduced pressure was purified by column chromatography on silica gel (2:1 hexane/ethyl acetate) to obtain 0.26 g of the title compound as colorless crystals.
