Ethyl 6-amino-5-cyano-4-isopropyl-2-methyl-4H-pyran-3-carboxyl-ate
Abstract:
In the title compound, C(13)H(18)N(2)O(3), the two H atoms of the NH(2) group are engaged in hydrogen bonding with the N atom of the cyano group and with one O atom of the ethoxy-carbonyl group, building a chain parallel to the [100] direction. The N-H⋯N hydrogen bonds assemble the mol-ecules around inversion centres, forming dimers with an R(2) (2)(12) graph-set motif.

Naming Amides
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.

Naming Acid Halides
The IUPAC and common names of acid halides are derived from the corresponding carboxylic acids, by changing “ic acid” to “yl halide.” For example, as shown below, the IUPAC name ethanoyl chloride is derived from ethanoic acid, and the common name, acetyl chloride, is obtained from acetic acid.
