In the title compound, C12H16FNO3, the dioxane ring adopts a chair conformation with the methyl groups and amine N atom in equatorial positions. The best plane through the dioxane ring makes a dihedral angle of 43.16 (8)° with the phenyl ring. In the crystal, pairs of C-HO hydrogen bonds link the molecules into centrosymmetric R22(8) dimers, which are linked into  chains by further C-HO hydrogen bonds. The N-H group does not participate in hydrogen bonding.
Dioxane rings are frequently encountered in structural motifs in many bioactive molecules such as cytotoxic agents (Aubele et al., 2005) and antimuscarinic agents (Marucci et al., 2005). For applications of this class of compounds, see: Wang, Yuan, Liu et al. (1996); Wang, Yuan, Lei & Liu (1996); Yuan et al. (2005). For related crystal structures, see: Chuprunov et al. (1981).
