9.2 g of 3-(2-chloro-phenyloxy)-1,2-epoxy-propane are added to a solution of 9.0 g of 6-(2-aminoethoxy)-nicotinic acid amide in 200 ml of isopropanol and the mixture is heated under reflux for 4 hours. After evaporating off the solvent under reduced pressure, 1-[2-(5-carbamoyl-2-pyridyloxy)ethyl-amino]-3-(2-chloro-phenoxy)-2-propanol is obtained; its hydrochloride melts at 202°-204° C. after recrystallisation from methanol.
