title: 6-Ethyl-5-fluoro-2-methoxy-pyrimidin-4(3H)-one.
abstract: In the title compound, C(7)H(9)FN(2)O(2), the meth-oxy and ethyl groups form dihedral angles of 1.4 (2) and 73.5 (3)°, respectively, with the mean plane of the pyrimidine ring. In the crystal structure, two mol-ecules are linked by a pair of N-H⋯O hydrogen bonds, forming a centrosymmetric dimer.
