N-(2,5-Dimeth-oxy-phen-yl)-N'-[4-(2-hy-droxy-eth-yl)phen-yl]urea
Abstract:
In the title compound, C(17)H(20)N(2)O(4), the 2,5-dimeth-oxy-phenyl unit is essentially planar, with an r.m.s. deviation of 0.015 Å. The dihedral angle between the benzene rings is 43.66 (4)°. The mol-ecular structure is stabilized by a short intra-molecular N-H⋯O hydrogen bond. In the crystal, inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules into a three-dimensional network.

Nomenclature of Carboxylic Acid Derivatives: Amides and Nitriles
The IUPAC and common names of amides are derived from the parent carboxylic acid, by replacing the suffix “oic acid” and “ic acid,” respectively, with “amide.” In the following example, the IUPAC name ethanamide is derived from ethanoic acid, and the common name, acetamide, is obtained from acetic acid.
