WebDPPA is always hit or miss in my experience. I've had reactions that work wonderfully with it and some that work horribly and never seem to go well (Mitsunobu reactions in particular). I'd say make the mesylate or tosylate and do a simple displacement with NaN3 (very easy reaction though you have to use sodium azide). Studies show that DPPA reacts with amines giving the corresponding phosphoramidates; it therefore appears that formation of the amide similarly involves the intermediate anhydride, followed by nucleophilic substitution by the amine.
