Acetic Acid Mixture with Hydrobromic Acid → HCID 20247127, compound

Participants

Reaction Steps

To 4.0 ml of a 30% hydrogen bromide-acetic acid mixture, was added 1.0 g of 4-amidino-2-benzoylphenyl 3-benzyloxycarbonylaminopropionate methanesulfonate. The mixture was stirred for one hour at room temperature to dissolve the crystals, forming a homogeneous yellow solution. Anhydrous ethyl ether was added to the solution to precipitate a white or pale yellow powder. After removing the supernatant, the residue was washed a few times with ethyl ether to obtain 0.5 g of a hydroscopic powder of 4-amidino-2-benzoylphenyl 3-aminopropionate dihydrobromide.
