Synthesis of derivatives of 5-azabenzofuran with functional substitutes in positions 4 and 7
- 37 Downloads
Methods for synthesizing derivatives of 5-azabenzofuran with functional substitutes in position 4 and 7 have been elaborated. The reactions of electrophilic substitution in position 7 have been studied.
An examination was made of the substitution of halogens in position 4 of derivatives of 5-azabenzofuran by the methoxy-group during the action of dimethyl sulfate in an aqueous alkali medium.
