Abstract
"PROCEDURE FOR THE PREPARATION OF OXAZOLIC COMPOUNDS", characterized in that it consists of the general formula: ** (See formula) ** where R1 represents hydrogen or an alkyl, aryl or aralkyl group containing up to 8 carbon atoms and R2 and R3 which may be the same or different from each other, each represents an alkyl or hydroxyalkyl group containing from 1 to 4 carbon atoms, by the fact that a α -hydroxy-acyloyl-phanone is cycled with carbamoyl chloride whose acyl residue is derived from an alkyl or aralkyl-carboxylic acid containing up to 10 carbon atoms to obtain an oxazolonium intermediate consisting of a 4-phenyl-oxazolone-2. which can be substituted at position 5 with an alkyl, aryl or aralkyl group containing up to 8 carbon atoms. That said oxazolonium intermediate is then chlorinated in position 2 by a chlorinating agent to obtain a second intermediate constituted by the corresponding 2-chloro-oxazole, and finally the said second intermediate is reacted with a suitable amine to obtain an oxazole compound of formula 1 .
