On June 23, 2011, Hardy, Larry Wendell; Heffernan, Michele L. R.; Wu, Frank Xinhe; Spear, Kerry L.; Saraswat, Lakshmi D. published a patent.Reference of 2-Amino-6-bromonicotinic acid The title of the patent was Preparation of substituted quinazolinones and their analogs for treating disorders mediated by metabotropic glutamate receptor 5. And the patent contained the following:
The title compounds I [R1 = H, alkyl, heteroalkyl, etc.; R2 = H, alkyl, cycloalkyl, etc.; R3 = H, alkyl, heteroalkyl, etc.; G = CHR2 or NR2 when b and c are both single bonds, or G = CR2 or N when one of b and c is a double bond; Q = NH or CH2 when d and e are single bonds, or N or CH one of d or e is a double bond; X = CH or N when f is a single bond, or C when f is a double bond; Z = CH2, C(O), C(S) or a bond when b is a single bond, or CH or N when b is a double bond; Y1-Y3 = CH, C(halo), C(alkyl), N (provided that no more than one of Y2 and Y3 = N); L1 = CC, HC=CH, CH2CH2, etc.] which modulate the activity of metabotropic glutamate receptor 5 (mGluR5) in the central nervous system or the periphery, and therefore are useful for the treatment, prevention, and/or management of various disorders, such as neurol. disorders, neurodegenerative disorders, neuropsychiatric disorders, disorders of cognition, learning or memory, gastrointestinal disorders, lower urinary tract disorder, and cancer, were prepared Thus, Pd-catalyzed coupling of 7-bromoquinazolin-4(3H)-one with 1-ethynyl-4-fluorobenzene afforded II. Exemplified compounds I were tested in in vitro cell-based assay for modulation of the activation of mGluR5 by glutamate (data given for representative compounds I). Pharmaceutical formulations containing the compounds I and their methods of use are also provided herein. The experimental process involved the reaction of 2-Amino-6-bromonicotinic acid(cas: 1196157-51-3).Reference of 2-Amino-6-bromonicotinic acid
