You can get your number at once with

BaseForm[Product[Prime[n], {n, 1, 1000}], 16]

If you want to have it in a text file one thing you can do is something like
this:

In[1]:=
temp = OpenWrite["file.txt", FormatType -> OutputForm]

In[2]:=
Write[temp, BaseForm[Product[Prime[n], {n, 1, 1000}], 16]]

In[3]:=
Close[temp]
Out[3]=
"file.txt"

This will produce a text file file.txt in your current Directory[],
containing the number you want in something resembling Mathematica's output
form. I suspect this is not exactly the form you want (it will contain the
character / at every line-break and a subscript 16 at the end to remind you
that you have an expression in base 16) but you can easily edit it in your
text editor. This seems easier than writing a program to produce just the a
long line of hexadecimal digits.
