Procedure
Free acid of SNAC (i.e. N-(8-[2-hydroxybenzoyl]amino)caprylic acid) was prepared as follows. The monosodium SNAC prepared in Example 12 was acidified with 1 equivalent of concentrated hydrochloric acid in water and stirred. The solution was then vacuum filtered and vacuum dried to yield the free acid.
