5-(D-arabino- tetrahydroxybutyl)-2- methyl-3-pyrroylhydrazine (1) was treated with phthalic anhydride (2) to give N-[5-(D-arabino-tetrahydroxybutyl)- 2-methyl-3-pyrroylRB- o-carboxybenzoylhydrazine (4) in 85% yield; its i.r. spectrum showed C=O, CO₂H, and NH and OH bands. Boiling this compound with acetic anhydride for 1 h afforded N-[1-acetly-2-methyl-3-pyrroyl-5- (D-arabino-tetraacetoxybutyl)]- N-phthalimidoacetamide (4).
