How do you kill Shandalar?

I wanted to give this a go with a solo f/m/c. I'd just killed Drizzt and I thought, mmm, who next should fear my wrath and ire... So, for no plot reason whatsoever, I reckoned I could shank Shandalar. Turns out he's almost impossible to hit, casts spells uninterrupted, and after a while he dimension doors away.
Has anyone done this? And what is the reward? I know he can be pickpocketed for a good set of level 4 spells.
