Reaction Steps

22.9 g (72 mmol) of 1-[2-(N-benzyl-N-methylamino)ethyl]-2-benzimidazolinone hydrochloride are dissolved in 250 ml of methanol, treated with 2.5 g of palladium-on-carbon (10%) and hydrogenated at room temperature for 90 minutes. The residue obtained after filtration and concentration is recrystallized from methanol/ether, whereby there are obtained 15.5 g (94%) of 1-[2-(methylamino)ethyl]-2-benzimidazolinone hydrochloride, m.p. 177°-180°.
