| titleOfInvention | A PROCEDURE FOR THE PREPARATION OF NEW ANILINOBENZOXAZOLES. |
| abstract | A procedure for the preparation of new anilinobenzoxazoles of the formula: **(See formula)** where X is hydrogen, C1-C4 alkyl, C1-C3 alkoxy, carboxy, C1-C3 carboxyalkyl, C1-C3 aminoalkyl, (C1-C3) monoalkyl, (C1-C3) dialkyl, (C1-C3) alkyl (C1-C3) alkyl), (C1-C3) alkyl (C1-C3) anilinoalkyl or (C1-C3) alkoxy (C1-C3) alkyl; R1, R2, R3 and R4, taken separately, are hydrogen, bromine, chlorine, fluorine, trifluoromethyl, carboxy, C1-C3 carboxyalkyl, C1-C3 alkyl, C1-C3 alkoxy or amino, such that one of the radicals R1 or R4 must be hydrogen on the same molecule and only two of the radicals R1, R2, R3 and R4 are other than hydrogen; R5, R6, R7 and R8, taken separately, are hydrogen, bromine, chlorine, fluorine, trifluoromethyl, carboxy, C1-C3-alkyl, C1-C3-alkoxy, C1-C3-alkoxy, C1-C3-alkyl, phenyl or nitro, such that only one of the radicals R5, R6, R7 and R8 is nitro, only one is phenyl, and only two of the radicals R5, R6, R7 and R8 are other than hydrogen; R5 and R6, R6 and R7 or R7 and R8, taken together, constitute the atoms necessary to form a fused aryl ring at positions 2,3 or 3,4; with the proviso that any one of the radicals X, R5, R6, R7, or R8 is a substituent other than hydrogen and with the proviso also that when any of the radicals X, R1, R2, R3, R4, R5, R6, R7, or R8 is alkyl, one of the radicals X, R1, R2, R3, R4, R5, R6, R7 or R8 is a substituent other than hydrogen or alkyl; whose procedure is characterized by reacting a 2-chlorobenzoxazole of formula **(See formula)** with a substituted aniline of the formula **(See formula)** where in said formulas II and III, R1 to R8 and X are those defined above, in an inert solvent and at elevated temperature.
