Procedure

A solution of 6.1 parts of N-methoxy-N-methylamine in 100 parts of diethyl ether was added to a solution of 33.6 parts of 5-(4'-isocyanato-2'-trifluoromethylphenoxy)-benzisothiazole in 300 parts of diethyl ether at from 20 to 30° C., the reaction mixture was stirred for 12 hours at this temperature and the resulting precipitate was then isolated. 33 parts (83% of theory) of 5-[4'-(N-methoxy-N-methylaminocarbonylamino)-2'-trifluoromethylphenoxy]-benzisothiazole of melting point 197° C. were obtained.
