Versuchsvorschrift

A mixture of 4.0 g of 5-(2-chloropyrid-5-ylmethyl)-3-methyl-4-nitroimino-perhydro-1,3,5-oxadiazine and 20 ml of concentrated hydrochloric acid is stirred for 2 hours at 80° C. The reaction mixture is cooled to 5° C., adjusted to a pH of about 5 with concentrated caustic soda solution and filtered. The filtering residue is mixed with diethyl ether/ethyl acetate 1:1 and filtered again. The title compound is thus obtained.
