Abstract: The title compound, C13H18O4, is an intermediate product in the synthesis of quinazoline derivatives. Crystal structure analysis shows that the benzene-butoxy Car-O-C-C torsion angle is 175.3 (2)° and that the benzene-methoxycarbonyl Car-C-O-C torsion angle is 175.2 (2)°. Torsion angles close to 180° indicate that the molecule is almost planar.
