Synthesis, Characterization, Crystal Studies of (E)-3-(3-(4-Fluorophenyl)-1-isopropyl-1H-indol-2-yl) Acrylaldehyde


We have synthesized and developed single crystals of the title compound (E)-3-(3-(4-fluorophenyl)-1-isopropyl-1H-indol-2-yl) acrylaldehyde, which is a key intermediate of anti-cholesterol fluvastatin drug. It crystallized under orthorhombic system with a space group Pna21. The dihedral angle between the indole mean plane and 4-F-phenyl ring was observed to be 111.5 (3)° in the title molecule. Further, strong hydrogen bonds were not found in the crystal structure.
