C 14 H 15 NO 2 (293 K): monoclinic space group P2 1 /n, a = 24.580(10), b = 5.536(2), c = 9.037(3) Å, β = 91.18(4)°, V = 1229.4(8) Å 3 , D x = 1.239 g · cm ‐3 , Z = 4, F(000) = 488, λ(CuKα) = 1.5418 Å, μ = 0.667 mm ‐1 . The title compound which was isolated from the rhizomes of Piper lolot C.DC has antibacterial activity. Its chemical identity was established by this X‐ray analysis. The molecule consists of a planar propanoyl pyrrole and a methoxyphenyl fragment with an interplanar angle of 93.8(3)° which is by 30° larger than the corresponding angle reported in the literature for the comparable dimethoxy derivative, which was also derived from Piper species.
