It may not be possible. Air conditioners that go through brick walls have
special air routing. On a window a/c the louvers in the cabinet are on the
sides. Air is drawn in through these openings and blown through the
condenser and then out the back. For the application you describe, the use a
different method. The air goes in through one side of the rear panel and out
the other side, it makes like a 'U' turn. If you put a window unit in the
wall and the side louvers are covered by the wall it won't work properly or
I've done four of them. As long as the side vents are not blocked (by the
thicker wall), it will work properly. Hardest part of the job is cutting
the brick. I used a circular saw with an abrasive blade made for masonry.
Finish with a chisel
Larger units with a slide out chassis are the easiest. You mount the casing
and then slide in the unit. You may want to frame out the opening with 1 x
6 (or whatever thickness) and then screw the box into it.
Be sure there are no pipes, wires, heat ducts, air returns, in the walls
first. Safe place is often under an existing window.

There are a/c units specifically made for wall installation. I don't know
how long they typically last, but the one I have appears to be almost 40
years old (before the manufacturer used their current serial number
system). On the other hand, a 2nd floor window shaker that looks like
current models (installed by previous owner) only lasted me 1 summer.
Something to consider is that future wall shakers may not be the same size
as current models.
If you do not want to hack up your nice brick wall, you may want to
consider a mini-split unit. It has the evaporator inside and condensor
outside, connected with freon lines and power (small hole). They are more
expensive, but do not require chopping a big hole out of your brick wall.
