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...
