Fixing a Hole (where the cold gets in)

What's the best (most weatherized and solid) way to fill in a 22" square window well in a south facing concrete wall that happens to one side of my house?

The south side of my house, a concrete wall, has a big draft. I opened the sheetrock in the basement to take a look and found one likely source: a 22"x22" hole, filled with bricks and mortar, which is crumbling at the top. I saw a sliver of daylight instantly. It looks like an old window that was filled in.
Should I remortar the bricks? Pull them all out, fit forms and pour concrete? Something else?
If I pour, should I drill some holes into the existing concrete for better adhesion/joining? Add rebar? Thanks in advance.
Once I'm done, I plan to fill the gap between the sheetrock and the concrete wall with that solid styrofoam-covered-with-foil insulation, but am open to suggestion.
