FIELD: chemistry.
SUBSTANCE: invention relates to a method of producing oxazoles of formula IV 
through condensation of aromatic aldehydes with α-ketoximes with formation of the corresponding N-oxides and their subsequent reaction with sulphonyl or thionyl compounds, preferably with inorganic thionyl halides or organic sulphonyl halides.
EFFECT: method is characterised by high output and purity of the obtained product, as well as avoiding the need to extract unstable intermediate N-oxides in form of individual compounds.
