Reaktionsschritte

A solution of 0.85 g of acetyl chloride in 5 ml of benzene is added dropwise to a solution of 2.8 g of 4-(4-aminophenoxy)-1-methyl-4-phenylpiperidine and 1.1 g of triethylamine in 10 ml of benzene. After stirring the mixture at room temperature for 6 hours, it is concentrated; the resulting residue is taken up with 30 ml each of water and diethyl ether; the obtained mixture is shaken thoroughly, and the organic phase is separated off, dried over sodium sulfate and concentrated. 2.8 g of the title compound remain as a viscous yellow oil which crystallizes (m.p. 143° to 144° C.) from diethylether after standing for several days.
