Abstract: In the title compound, C₁₄H₁₄F₂N₂O₃, the dihydropyrimidinone ring adopts a flattened boat conformation. The difluorophenyl group is disordered over two orientations with occupancies of 0.544 (3) and 0.456 (3). The methoxycarbonyl group is disordered over two positions with occupancies of 0.580 (8) and 0.420 (8). In the crystal, molecules are linked into centrosymmetric dimers by paired N-HO hydrogen bonds and the dimers are linked into a ribbon-like structure along [100] by further N-HO hydrogen bonds.
