A phenyl ring as proton‐donor to carbonyl oxygen atoms and doubly bonded nitrogen atoms is present in the crystal of the title compound 1 . Compound 1 forms almost completely planar “dimers”. These findings are of interest, inter alia, in connection with the conformation of aromatic side chains in peptides.
