実験手順

The mixture of 4.0 g of 2-(2-tosyloxyethyl)-6,7-dichloro-1,4-benzodioxan, 1.69 g of 1-(4-piperidyl)-2-imidazolidinone, 10 g of ahydrous sodium carbonate and 100 ml of 4-methyl-2-pentanone is stirred and refluxed for 2 days. It is filtered, evaporated and the residue recrystallized from acetone, to yield the 1-[1-[2-(6,7-dichloro-1,4-benzodioxan-2-yl)-ethyl]-4-piperidyl]-2-imidazolidinone melting at 165°.
