6-Chloro-2-aminobenzamide (cas: 54166-95-9) belongs to amides. In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well. Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. The presence of the amide group –C(=O)N– is generally easily established, at least in small molecules. It can be distinguished from nitro and cyano groups in IR spectra. Amides exhibit a moderately intense νCO band near 1650 cm−1. By 1H NMR spectroscopy, CONHR signals occur at low fields. In X-ray crystallography, the C(=O)N center together with the three immediately adjacent atoms characteristically define a plane.SDS of cas: 54166-95-9

Direct and metal-free oxidative amination of sp3 C-H bonds for the construction of 2-hetarylquinazolin-4(3H)-ones was written by Liu, Huanhuan;Zhai, Tianran;Ding, Shiteng;Hou, Yalei;Zhang, Xiangyu;Feng, Lei;Ma, Chen. And the article was included in Organic Chemistry Frontiers in 2016.SDS of cas: 54166-95-9 This article mentions the following:

A new method for the synthesis of 2-hetarylquinazolin-4(3H)-ones I [R1 = H, 6-Me, 5-Cl, 6-C6H5CC, etc.; R2 = H, Me, Pr, iso-Pr, benzyl, oxolan-2-ylmethyl, 2-(3,4-dimethoxyphenyl)ethyl; R3 = quinolin-2-yl, 7-chloroquinolin-2-yl, 8-(benzyloxy)quinolin-2-yl, etc.; X = C(O), SO2] from 2-aminobenzamides R1-2-H2NC6H3C(O)NHR2 and (2-azaaryl)methanes such as 2-methylquinoline, 2-methylbenzo[d]thiazole, 2-methylquinoxaline, etc. under transition metal-free conditions has been described. This protocol features a wide substrate scope with a broad range of functional group tolerance under mild conditions. The oxidation of (2-azaaryl)methanes to (2-azaaryl)methanals is proposed as the key step in this transformation. In the experiment, the researchers used many compounds, for example, 6-Chloro-2-aminobenzamide (cas: 54166-95-9SDS of cas: 54166-95-9).
