Reaktionsschritte

To a solution of 1,3 dichloroacetone (0.84 g, 6.62 mmol) in toluene (5 ml) was added 4-methylthiobenzamide (0.50 g, 3.31 mmol) and the reaction mixture was heated at 120° C. for 1 h. After the completion of the reaction mixture (TLC monitoring), the reaction mixture was evaporated to dryness under reduced pressure and the residue was purified over silica gel (230-400 M, 15% EtOAc-Hexane) to get the desired product (0.49 g, 67%). The other derivatives were also prepared by the same general method.
