X-ray, NMR, and theoretical studies of the nootropic agent BMY-21502, a pyrrolidinone derivative.
The preferred crystalline, solution, and in vacuo arrangements of 1-[[1-[2-trifluoromethyl)-4-pyrimidinyl]-4-piperidinyl]methyl]-2-pyrroli dinone (BMY-21502) were investigated by means of single-crystal X-ray diffraction, 1H and 13C NMR spectroscopy, and semiempirical molecular orbital and molecular mechanics calculations. The X-ray powder diffraction pattern is also reported.
