Reaction Steps

1.52 g of sulfodehydroabietic acid monohydrate is dissolved in 5 ml of methanol, and a solution of 0.907 g of L-glutamine cyclohexylamide in 20 ml of methanol is added thereto. The mixture is concentrated under reduced pressure to remove solvent until the volume of said mixture is 5 ml. Ether is added to the residue and the precipitates (white crystalline) are collected therefrom. 1.35 g of sulfodehydroabietic acid L-glutamine cyclohexylamide salt hemihydrate is thereby obtained.
