3-Methyl-2-(3,3,3-tri­chloro-2-hy­droxy­prop­yl)quinazolin-4(3H)-one

The title mol­ecule, C₁₂H₁₁Cl₃N₂O₂, contains planar quinazolin-4(3H)-one (r.m.s. deviation = 0.0257 Å) and propyl fragments, forming a dihedral angle of 10.4 (2)°. An intra­molecular O—H...N hydorgen bond occurs. In the crystal, O—H...O hydrogen bonds link the mol­ecules into an infinite chain running parallel to the b axis.
