allocating memory for char array in free store

[etrusks]

Why I'm unable to create this array the 2nd way? How could it be done without at 1st creating this array (char arr[] = "Hello";) and only than creating pointer to it?
I'm getting this error message from compiler

Error 1 error C2440: 'initializing' : cannot convert from 'initializer-list' to 'char []'

int main(){
    char* p1 = new char[] {'H', 'e', 'l', 'l', 'o', '\0'};   // works
    char* p2 = new char[] {"Hello"};   //this gives error
}
