In a similar manner using 2.36 g. of 3-(β-aminoethylamino)-1-(2-cyanophenoxy)-2-propanol and 2.37 g. of ethyl 4-carbamoylmethoxyphenylacetate as starting materials there is obtained 3-β-(4-carbamoylmethoxyphenylacetamido)ethylamino-1-(2-cyanophenoxy)-2-propanol, isolated as its hydrogen oxalate, m.p. 123°-125° C. after crystallisation from ethyl acetate.
