Procedure

The evaporation residue obtained in Example 24(b) is dissolved in 300 ml of ethanol, after which 10 ml of concentrated hydrochloric acid is added. The mixture is refluxed for 30 min. The solution is treated with charcoal, and filtered. The solvent is evaporated giving a mixture of the (Z)- and (E)-isomers. The isomer mixture is recrystallized from petrol ether to give 7.7 g (22% from 5-chloro-1,2-diphenylpentan-1-one) of the (Z)-isomer, m.p. 116°-8° C.
