Abstract

Abstract The solid-state structure of (±)-N-desmethylnefopam hydrochloride (1), a metabolite of the analgesic drug, was determined by single-crystal X-ray diffraction analysis. Compound 1 gave crystalline prisms belonging to the orthorhombic Pcab space group, and at ambient temperature (293 K), a= 9.939 (2), b= 14.479 (1), c= 20.148 (3) A, V= 2899.5 (8) A 3, Z= 8, R (F)= 0.045, and R w (F)= 0.025. The benzoxazocine ring of crystalline 1 is ...
