Abstract: The method for preparing proline compounds of formula (I), used as the inhibitor against angiotensin and antihypertensive agent, is presented. Thus, 4.1g of N-(2-bromopropionyl)-proline benzylester is dissolved in 200 ml of chloroform and the above mixture is cooled in water-ice bath. Then, 1.7g of 2-bromopropionyl chloride is dropped slowly to the 15ml of chloroform solution containing the proline ester. The above mixture is stirred at 25≦̸C for 24 hrs and the obtained chloroform layer is washed with water three times, evaporated and purified using chromatograhy. In (I), R1 and R7 are each H, C1-10 lower alkyl or aryl; R2, R3, R5 and R6 are each H, C1-10 lower alkyl, aryl, amine or cyano ; R4 is H or C1-10 lower alkyl.
