zatimco LAH si tak dobre nevede..
20 grams of LAH was added to 200ml THF in a 1000ml two-necked RB flask, equipped with a magnetic stirrer, and it fizzed some, but not much. Now 20 grams of the above nitrostyrene was added dropwise as a solution in 200ml THF through a dropping funnel, which caused the solution to boil, and when all had been added, the solution was allowed to reflux for 24 hours. The reaction mixture was allowed to cool, and 15ml IPA, followed by 15ml 15% NaOH solution, 30 ml THF, and finally 50ml of cold water, as fast as the exothermic reaction allowed. The solution now became a white sludge, which was filtered through a pad of celite, and the filter cake washed with some additional THF. The solvent was removed under vacuum, and the residue dissolved in dilute H2SO4, and washed with 3x25ml CH2Cl2, made basic with 25% NaOH solution, and extracted with 3x30 ml CH2Cl2. The extracts was dried over MgSO4, filtered, and the solvent removed under vacuum. The residue was distilled at 3 mmHg to give 10 grams (57%) of a slightly yellow oil, 2,4-dimethoxy-3-methylphenetylamine.
