Procedure

10 g of the 2-(β-hydroxyethylamino)-6-nitro-toluene prepared under Example 3, stage 2 are transferred to a stainless steel autoclave together with 200 ml of methanol, about 2 g of Raney nickel are added, and catalytic reduction is carried out with hydrogen under a hydrogen pressure of 20 bar at 70° C. in the course of 6 hours. After the catalyst has been removed, the mother liquor is concentrated and the product is isolated and dried.
