Abstract
Abstract The compound of formula I ##STR1## wherein R 2 is methyl, ethyl, isopropyl or sec-butyl, can be prepared by selective chlorination of an appropriate milbemycin derivative either with hypochlorous acid (HOCl) or sulfuryl chloride (SO 2 Cl 2 ) in the temperature range from -10° to +60° C. It is employed as pesticide for controlling Arthropode species such as injurious insects or ecto- or endoparasites of animals, and is applied in the form of compositions. This compound is also used as intermediate for obtaining further milbemycin derivatives.
