Abstract
Procedure for the preparation of Amino-2-oxazolo- (4,5 b) -pyridine compounds, and their derivatives, characterized by the general formula: **(See formula)** in which: R represents: 1) either a hydrogen atom, 2) either a carbonyl group of the CO-R1 type, where R1 represents: a) either a lower alkyl, or cycloalkyl radical, b) either a substituted phenyl group of the general formula **(See formula)** wherein R2, R3, R4, R5 and/or R6 are identical or different and represent either a hydrogen or halogen atom, or a lower alkyl, alkoxy, trifluoromethyl or nitro radical. c) either a diarylalkyl group, aralkyl optionally substituted in the aryl nucleus in ortho, meta and/or para position, by one or more halogen atoms. d) either a styryl radical, optionally substituted in the ortho, meta and/or para position, by one to several halogen atoms, one or more lower alkyl, alkoxy, nitro radicals. e) either a styryl vinyl radical, thiophene-2 vinyl, furyl-2 vinyl, furyl, nitro-2 furyl, thiophenyl, pyridyl in ortho, meta or para position, cromonyl. f) either a phenoxyalkyl group of the general formula: **(See formula)** wherein R7, R8, R9, R10 and/or R11 are identical or different and each represent either a hydrogen atom, a halogen atom, and a lower alkyl, alkoxy, allyl, naphthyl, cinnamoyl radical optionally substituted by the phenyl nucleus in ortho, meta and/or para position, by one or more halogen atoms. g) either a phenylthioalkyl radical optionally substituted on the phenyl nucleus in the ortho, meta and/or para position, by one or more alkyl radicals. h) either an amino radical of the type -NH - R', where R' represents: - either a lower alkyl radical, - either a substituted phenyl radical, of the general formula: **(See formula)** wherein R12, R13, R14, R15 and/or R16 are identical or different and each represent either a hydrogen atom, or a halogen atom, either a lower alkyl, alkoxy, nitro radical or a radical allyl, paraalkyl-phenyl-sulfo, phenoxyalkyl, cycloalkyl, naphthyl, chromonyl, pyridyl, either a styryl group optionally substituted on the phenyl nucleus in ortho, meta and/or para position, by one or more halogen atoms, or radicals alkoxy, nitro. 3) either a sulfonated group of the type: **(See formula)** where R'1 represents either a hydrogen atom, a halogen atom, and a lower alkyl radical.
