Abstract
|
|
|
|
The crystal structure of KR-21042, N-(3-Phenylpropyl )-4-hydroxy-3-methoxyphenylacetamide, was determined by single crystal X-ray diffraction analysis. The compound was recrystallized from a mixture of ethylacetate and n-hexane in monoclinic, space group P2₁/c, with a = 16.622(1), b = 6.215(f), c = 15.802(1) A, β= 104.97(1), and Z = 4. The calculated density is 1.261 g/cm₃. The structure was solved by the direct method and refiled by full matrix least-squares procedure to the final R va1ue of 0.068 for 2332 observed reflections.
