85385-06-4 → N-(2',6'-dimethylphenyl)-1-methoxymethylethylamine

Participants

Reaction Steps

The general procedure described in Example B1 is repeated, with the following modifications to the reaction conditions: A catalyst solution is prepared consisting of 5.3 mg of [Ir((1,5-cyclooctadien)Cl]2 (0.0079 mmol), 10.2 mg of A (0.017 mmol) and 11.9 mg of tetrabutylammonium iodide (0.032 mmol) in 5 ml of tetrahydrofuran/dichloromethane (1:1). A substrate solution consisting of 1.5 g of N-(2′,6′-dimethylphenyl)-1-methoxymethyl-ethylideneamine (7.8 mmol) in 5 ml of tetrahydrofuran is also used. Hydrogenation is carded out with hydrogen under a pressure of 40 bar. The reaction temperature is 30° C. After 91 hours the conversion is 90%, the ee is 59% CR).
