Benzoyl chloride → HCID 33269723, compound

Participants

Reaction Steps

2.35 g (0.0087 mol) of L-alanyl-L-alanine ethylamide hydrobromide were suspended in 40 ml of pyridine and 2.04 ml (0.02 mol) of benzoyl chloride were added. The mixture was then stirred for 2 hours at room temperature. The solvent was evaporated and the residue recrystallised from isopropanol to yield 1.3 g (51%) of N-benzoyl-L-alanyl-L-alanine ethylamide of melting point 237°-239° C; [α]D20 =-17.8° (c=1.01% in methanol).
