There is probably a way to do this without first converting to base 10, but I'm not super sure how to do it.

Anyway, first convert 45 from base 6 to base 10, which is \(5+4\cdot6=29\).

The sum of the integers 1 to 29 base 10 is \(\frac{(29)(30)}{2}=435\). In base 6 that would be equal to \(\boxed{2003}\), which is our answer.
