Benzoyl chloride → {4-[2-(6-Methoxynaphthalen-2-yl)propyl]piperazin-1-yl}(phenyl)methanone

Participants

Reaction Steps

Benzoyl chloride (0.58 ml, 5 mmols) is added, at 0° C., to a solution of 2-(2-piperazino-1-methylethyl)-6-methoxynaphthalene (1.42 g, 5 mmols) and N-ethylmorpholine (0.65 ml, 5 mmols) in 15 ml of methylene chloride. The mixture is allowed to return to ambient temperature and stirred for 3 hours. The reaction medium is washed with water and dried over sodium sulphate. Concentration of the mixture yields an oily residue which dissolves in ether and crystallises. The compound is recrystallised from ethyl acetate (15 ml).
