Carbon‐13 nuclear magnetic resonance spectrum of methaqualone

Abstract

Abstract 13 C nmr chemical shifts of methaqualone, 2‐methyl‐3‐propyl‐4‐quinazolone, 2‐methyl‐3‐phenyl‐4‐quinazolone and their precursor, acetanthranil, are reported. The signals are assigned on the basis of suhstituent effects on benzene shifts, intensities, multiplicities in SFORD, and comparison with structurally related compounds.
