Procedure
5 mmol of 3-(1H-imidazol-4-yl)propyl chloride are introduced into a solution of 6 mmol of 3-phenylpropanethiol and 10 mmol of sodium in 30 ml of ethanol and the mixture is brought to reflux for 3 h. The suspension is evaporated under vacuum until dryness, potassium carbonate is added and the mixture is stirred in methanol/water. The residual semi-solid oil is brought to boiling in ethanol with active charcoal, filtered and recrystallized in the hydrogenmaleate form from ethanol/diethyl ether.
