FIELD: chemistry.
SUBSTANCE: invention relates to method of obtaining di-{ 4-[(tetrahydro -4H-1,4-oxazin-4-yl)-methylsulphanyl]-phenyl} ether oxalate of formula
as water-soluble substance with fungicidal activity. Essence of method consists in interaction of di-{ 4-[(tetrahydro -4H-1,4-oxazin-4-yl)-methylsulphanyl]-phenyl} ether with equimolar quantity of oxalic acid (COOH)2 at room (~20°C) temperature for 15 min.
EFFECT: output constitutes 99%.
