Procedure: In an adiabatic reactor, 100 ml of a copper oxide/chromium oxide catalyst (molar ratio CuO:Cr2O3 =2:1) containing 1.5% by weight of palladium are activated in the manner described in Example 2 and heated in the stream of hydrogen to 275° C. 60.6 g (0.5 mol) of 2,6-dimethylaniline, 76 g (1.0 mol) of 2-methoxyethanol and 67.2 N1 (3mols) of hydrogen are then passed, at 275° C. and under a pressure of 4 bars (absolute), through the catalyst bed. The reaction mixture which issues from the reactor is condensed and worked up by distillation. are then passed, at 275° C. and under a pressure of 4 bars (absolute), through the catalyst bed condensed worked up by distillation

Conditions: temp:275.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: In a quartz tube 30 cm in length and 0.5 cm in diameter, which is arranged vertically and surrounded by a heating jacket, 2 ml of this catalyst are activated at 130° C., in the manner described in Example 2, and then heated to 275° C. under hydrogen. At 275° C., 1.21 g of 2,6-dimethylaniline, 1.52 g of 2-methoxyethanol and 0.67 N1 of hydrogen are then passed, per hour, under normal pressure, through the reactor from top to bottom. The mixture which issues from the reactor is condensed and worked up by distillation. In a quartz tube 30 cm in length and 0.5 cm in diameter, which is arranged vertically are activated at 130° C., in the manner condensed worked up by distillation

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 2.0 g (0.0161 mole) of 2,6-dimethyl-cyclohex-2-en-1-one, 50 ml of toluene, 1.8 g (0.024 mole) of 2-methoxyethylamine and 0.5 g of palladium on charcoal (5%) are heated with a starting pressure of 17 bars (7 bars propylene and 10 bars nitrogen) for 10 hours at 180° C. After cooling, the catalyst is filtered off and the filter residue is washed with ether and toluene. The solvent is evaporated off to leave 1.0 g of crude N-(2-methoxyethyl)-2,6-dimethylaniline, from which is obtained, by distillation in high vacuum, 0.4 g (13% of theory) of pure N-(2-methoxyethyl)-2,6-dimethylaniline; b.p. 61°-62° C./ 0.1 Torr. After cooling the catalyst is filtered off the filter residue is washed with ether and toluene The solvent is evaporated off
