Erj-190 captain reported during climbout; with one pack on MEL; losing the other bleed and thus lost...

Narrative:

Departed ZZZ with pack 1 MEL. Passing FL260 had 'bleed 2 leak' (amber message). Because pack 1 was MEL we had no way to pressurize the aircraft. Airplane cabin alt started to climb; I was the PNF; and asked ATC for lower and ran the bleed leak checklist. After getting clearance to only 17000 MSL I [told] ATC we needed 10000 MSL. They ended up vectoring us off course and cleared us to 10000. After completing the checklist we continued a descent to 5000 MSL and landed at ZZZ1 uneventfully. The max cabin alt ended up climbing to 6900 ft.
