I have synthesized a compound along with this I am getting 22-25% DMA.HCl. The reason for this, the coupling of DMA gas to acid chloride intermediate of my compound leads formation of DMA.HCl. I know that the salt is water soluble but along with this my synthesized compound is also highly water soluble. The compound is not soluble in other polar and non polar solvents. Suggest some alternatives to remove salt.
