末（に）After a long process; in the end
Introduces the outcome reached after a long, involved, or difficult process. It directs attention not only to the result, but also to the substantial path leading to it.
What the pattern highlights
This pattern does more than place one event after another. The preceding part describes a process substantial enough to matter—perhaps repeated reconsideration, months of negotiation, or sustained effort—and the following part gives the endpoint. Natural translations include “after much...,” “after a long process,” and “finally, after....”
The main forms
The outcome may be welcome, neutral, or difficult. What remains constant is the emphasis on the path taken to reach it.

半年にわたる交渉の末に、両社は契約を更新しないことで合意した。

AnalyzeThe result is not presented as happy or unhappy; the emphasis is on the long negotiation that produced it.
度重なる検討の末の決定は、旧校舎を保存するというものだった。

Analyze末の directly modifies the result noun “decision.”
With or without the particle
末に clearly connects the completed process to the following result. The particle is often omitted in compact written phrasing, especially when the relationship between the process and result is already clear.
A neutral endpoint versus a disappointing one
末 can lead to a positive, neutral, or difficult outcome. あげく strongly favors a troublesome course ending in a disappointing or undesirable result. Because of that tendency, replacing the target in an entirely positive success story often sounds mismatched.

AnalyzeNatural: the long process ends in a clearly welcome outcome.
