Reaktionsschritte

A solution of 14.3 g of 1-[2-(cyclopropyl-methoxy)ethyl]-4-(2,3-epoxypropoxy)-benzene (German Offenlegungsschrift No. 2,649,605) and 16.3 g of 5-[2-(benzylamino)propoxy]-salicylamide in 200 ml of isopropanol is refluxed for 18 hours. The reaction mixture is concentrated by evaporation to leave crude 1-[N-[2-(3-carbamoyl-4-hydroxy-phenoxy)-ethyl]-benzylamino]-3-[4-[2-(cyclopropylmethoxy)ethyl]-phenoxy]-2-propanol in the form of brown oil, which can be further processed without additional purification.
