Procedure

A solution of 11.7 g of 1-{N-benzyl-N-[2-(3-carbamoyl-2-pyridyloxy)-ethyl]-amino}-3-(2-methyl-phenyloxy)-2-propanol in 120 ml of ethanol is hydrogenated in the presence of 1.2 g of a 5% strength palladium-on-charcoal catalyst at 20°-30° C. and under atmospheric pressure until the uptake of hydrogen ceases. The reaction product is worked up analogously to the process described in Example 1, giving crude 1-[2-(3-carbamoyl-2-pyridyloxy)-ethylamino]-3-(2-methyl-phenyloxy)-2-propanol. A solution of 1.5 g of fumaric acid in isopropanol is added thereto and the neutral fumaric acid salt of 1-[2-(3-carbamoyl-2-pyridyloxy)-ethyl-amino]-3-(2-methyl-phenyloxy)-2-propanol thus obtainable, is recrystallised from a mixture of isopropanol and water; melting point 156° C.
