Use a lookup table and an xor operation:

ld b,0
ld hl,BitMasks
add hl,bc
ld b,(hl)
xor b
BitMasks:
.db $1, $2, $4, $8, $10, $20, $40, $80
That's an interesting way of doing that, but if you only need one,
then use the xor command alone.
They say one has to be good in this business. Well I'm better.
