Process for preparing nitrogen-containing heterocyclic compounds
Nitrogen-containing heterocyclic compounds are prepared by cyclization of a compound having the formula: CH2-CH2 X-N ANGLE ANGLE N-CH2-CHR-Y CH2-CH2 or H(-N-CH2-CH2)n-N-CH2-CHR-Y ¦¦ XX wherein X represents a hydrogen atom or -CH2CHR-Y; R represents a hydrogen atom or methyl atom; Y represents an -OH...

Zusammenfassung: | Nitrogen-containing heterocyclic compounds are prepared by cyclization of a compound having the formula: CH2-CH2 X-N ANGLE ANGLE N-CH2-CHR-Y CH2-CH2 or H(-N-CH2-CH2)n-N-CH2-CHR-Y ¦¦ XX wherein X represents a hydrogen atom or -CH2CHR-Y; R represents a hydrogen atom or methyl atom; Y represents an -OH group or -NH2 group; and n represents the integers 0 or 1 - 4; with a zeolite catalyst having the formula a(M2/nO). (Al2O3) . m(SiO2) wherein M represents a cation selected from alkali metals, alkaline earth metals, zinc group elements, hydrogen and ammonium cations; n represents the valence of the cation; a is 1.0 +/- 0.5 and m is 2 - 12. |
