Reaktionsschritte

N-Chlorosuccinimide (37.4 g, 0.28 mole) was added portionwise to 2-(2-methoxy-5-bromophenyl)-2-methyl-1-propyl methyl sulphide (79.3 g, 0.275 mole) in carbon tetrachloride (250 ml) at room temperature. An exothermic reaction ensued, the temperature being allowed to rise to 40° C. before control with an external cooling bath was applied. After addition, the reaction mixture was heated at about 40° C. for 4 hours, then cooled, filtered and run down yielding 88 g crude title product (99%).
