Abstract
Pronalazak se odnosi na postupak za dobijanje hlorbenzoksazola formule (I) gde su R1, R2 i R4 definisani kao u zahtevu jedan i u slučaju (a) R3 predstavlja vodonik, halogen, CN, NO2 C1-C5-alkil, C1-C5-alkoksi, aril ili ariloksi, pri čemu je svaki od poslednja četiri navedena ostatka supstituisan ili nesupstituisan ili u slučaju (b)R3 je hlor, karakterističan po tome što se benzoksazoli formule (II) kod kojih R1, R2 i R4 imaju isto značenje kao u formuli (I) i R3 u slučaju (a) kao u formuli (I), odnosno R3 je u slučaju (b) vodonik dovode u reakciju u prisustvu nekog kiselog katalizatora sa sredstvom za hlorovanje i prevode u produkt monohlorovanja (I) odnosno u slučaju (b) sa viškom sredstva za hlorovanje u produkt dihlorovanja (I), gde R3 predstavlja hlor.[The invention relates to a method for producing chlorobenzoxazolene of formula (I), wherein R1, R2 and R4 are defined as in Claim 1 and in (a) R3 = H, CN, NO2, C1-C5-alkyl, C1-C5 alkoxy, aryl or aryloxy, whereby each of the four radicals mentioned is unsubstituted or substituted, or in (b) R3 = chlorine. The inventive method is characterized in that benzoxazole of formula (II) wherein R1, R2 and R4 have the same meaning as in formula (I) and R3 in (a) is defined as in formula (I) or R3 in (b) is hydrogen, reacts in the presence of an acid catalyst with a chlorinating agent to form a monochlorination product (I) or in (b) reacts with an excess of a chlorinating agent to form a dichlorination product (I), wherein R3 = chlorine.
