C-Corp Help

Got a question about corporations and liquidations.

Here is the scenerio: Got a C-corp with 5 equal shareholders. Assets are around $300,000 with 75% of this being land. Shareholders are getting old and would like to sale the land.

Question: Is there a way to avoid doulble taxation of the gain on the sale?

I have researched liquidations but if I understand it correctly, the tax on this is the same as selling the assets through the corporation. Am I missing something here?

Thanks for the help!
