Komponenten

Versuchsvorschrift

A mixture of 1-(4-chlorobenzyl)piperazine (21.05 g; 0.1 mole), anhydrous potassium carbonate (20.7 g; 0.15 mole) and 2-chloroethanol (8.85 g; 0.11 mole) in butanone (270 ml) was stirred at reflux for 61/2 hr, cooled, and the solvent removed in vacuo. Chromatography of the residue on silica eluting with chloroform gave 8.74 g (34%) of the title compound as an oil, νmax (film) 3350, 2910, 2800, 1595 cm-1 ; (Found; C, 61.48; H, 7.96; N, 10.13; C13H19N2ClO requires; C, 61.28; H, 7.52; N, 11.00%).
