実験手順

Of the crude N,N-dimethyl-2-[methyl-(2-pyridine-4-yl-ethyl)-amino]-acetamide, 44 g are dissolved in 500 ml of glacial acetic acid and hydrogenated with 4 g of PtO2 at ambient temperature under 3 bar H2. After the catalyst has been removed by suction filtering the filtrate is evaporated down. The residue is made alkaline with 50% potassium hydroxide solution while cooling with ice and the product obtained is taken up in ether. The ether solution is dried over sodium sulphate, filtered and the solution is evaporated down. The product is left as a yellow oil. Yield: 42 g
