@oxide I just don't like the reaction, titration of store bought bleach is a pain and temperature control during the reaction is hard. It may be different now that I upgraded my hotplate, but I'm in no rush to do it again
The bleach titration is a little tedious, but nothin too bad. As for the temperature, just lots of salt and ice does the trick for me.

I've decided I'm going to do it one more time (even though I have a lot of anthranilic acid), I want to test a recryst of the crude product (which is almost white) with solvents other than water (MeOH, ether, chloroform/heptane, etc). I have a feeling that may yield some nicer crystals.

My inability to do reactions under a 3 gram scale has been my downfall. But when it works its the greatest feeling ever :D

I know how you feel! When I do a reaction on a small scale, even when it works it's not too exciting. I try to keep smaller scale reactions to test runs or POC's.
