Reaction Steps

14 g of 2-bromo-1-(2,4-dichlorophenyl)-1-propanone (Compound 1), 17.1 g of N-(α-cyclopropyl-4-bromobenzyl)-N-propylthiourea (Compound 64) and 7.6 ml of triethylamine are dissolved in 200 ml of ethanol And the solution is heated to 65° C. The reaction is monitored by TLC. At the end of the reaction, the ethanol is removed and the residue is hydrolysed with water and extracted with methylene chloride. The organic phases are washed and dried. The product is purified on a column of silica, using a mixture of cyclohexane and ethyl acetate (20:1 v/v) as eluent.
