Doubt with Assembly - Change Address value

Question

I am beginner in Assembly and C, and I need to change the value of an . exe file address

004864D2   . C785 5CFCFFFF F8020000    MOV DWORD PTR SS:[EBP-3A4],2F8

I tried it this way with the C

__declspec(naked) void HookPatch::ChangeCliver_02()
{
    static const INT32 szContinue = 0x0048652C;
    __asm
    {
        MOV DWORD PTR SS : [EBP - 0x03A4], 0x1DF2
        JMP szContinue
    }
}

When I run the program with Ollydbg the quoted line is deleted.
