The synthetic route is as follows., SDS of cas: 6941-75-9
Synthetic Example 3; Synthesis of 4-bromophthalamide (hereinafter abbreviated as 4-BPA); [Show Image] 4-BPA represented by the formula (21) was synthesized from 4-bromophthalimide (hereinafter abbreviated as 4-BPI) according to the following procedure (reaction formula 3) with reference to Journal of Heterocyclic Chemistry, 1995, pp. 495-498. In a 100-ml eggplant flask, 27.8017 g (0.123 mols) of 4-BPI and 60 ml of 20% ammonia water were placed followed by reaction under stirring at 23C for 48 hours. After completion of the reaction, the reaction solution in the form of a white suspension was allowed to stand at 0C for one hour, followed by filtration under reduced pressure. The resulting white solid was dried in a reduced pressure dryer at 23C or 24 hours to obtain 29.90 g (yield: 75%) of a white powder of 4-BPA. The thus obtained white powder was subjected to identification of the structure thereof from NMR spectra and confirmed as 4-BPA. 1H-NMR (ppm/DMSO-d6):delta 7.84(s, 1H), 7.78(s, 1H), 7.67(d, 1H), 7.65(d, 1H), 7.62(d, 1H), 7.43(s, 1H), 7.40(s, 1H).
