Unable to insert to std map

I have a std map consisting of int and pointer to a struct. However using the insert function I am unable to add the same. The error message seems bit too tricky for me to get to the bottom.

#include <iostream>
#include <map>
using namespace std;

typedef struct 
{

}NODE;

int main()
{
    std::map<int, NODE*> mp;
    int i = 0;
    mp.insert(i, new NODE());

    return 0;
}

The error language is bit cryptic. I am trying to add an int and a NODE pointer to map of int and NODE pointer. Why is this giving me un-matching function?

main.cpp: In function ‘int main()’:
main.cpp:22:28: error: no matching function for call to ‘std::map::insert(int&, NODE*)’
     mp.insert(i, new NODE());
