Purification of compound containing dicarboxylic acid and amine

The prep-LC in my lab is broken and I need to urgently purify [my compound](https://i.stack.imgur.com/breeX.jpg) which contains two carboxylic acid groups, one amine, and one amide bond. This compound was synthesized with [the scheme](https://i.stack.imgur.com/breeX.jpg) and it did dissolve well in the reaction solvents, which are DMF and water, but it does not seem to dissolve in any other organic solvents... I am having a difficulty in finding out a suitable TLC eluent system because of this issue. Can anybody please advise me what to do?
