catalytic effect of a neighboring pyridinium group is based upon interaction of the negatively charged transition state of esterhydrolysis with the electron deficient π-system of the pyridinium ring. For the -methoxy-phenolate ester containing the 3-aminocarbonylpyridinium group in the position this interaction leads to a change in mechanism from rate limiting hydroxide ion attack to hydroxide ion catalyzed
