A novel pyrrolizidine derivative of the formula,
has potent antiarrhythmic activity and low toxicity.
The derivative can be synthesized: by acylating 2,6-xylidine to protect the amino group, nitrating the protected xylidine to introduce a nitro group at 3-position, reducing the nitro group to an amino group, followed by diazotizing and hydrolyzing, and then the resulted 3-hydroxy-2,6-dimethylaniline being condensed with 8-halocarbonylmethyl- pyrrolizidine; or by nitrating N-(2',6-'-dimethyi)phenyl-8-pyrrolizidineacetamide to introduce a nitro group at 3'- position, reducing the nitro group to amino group, diazotizing the amino group and hydrolyzing the diazonium compound.
