How is it possible for the demon to attack the wizard when it can't cross the pentagram and it has no ranged attacks?

I suggest this clarification:

If there is a pentagram, the wizard must be on the same side as the demon for the contest of wills to take place. So if a wizard summons a demon into a pentagram, the wizard must enter the pentagram with the demon in order to gain a wish.

Another possible answer is that the wizard, having initiated the contest of wills between himself and the demon, has invalidated the pentagram's protection for himself.
