Reference of 934266-82-7, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 934266-82-7, name is 5-Bromothiazolo[5,4-b]pyridin-2-amine. This compound has unique chemical properties. The synthetic route is as follows.
Step B: 4-acetylbenzoyl chloride (3B, 560 mg, 1.0 equivalent) was dissolved in DMA (0.15 M). Methyl 4-(chlorocarbonyl)benzoate (2.0 equivalent) was then added. The mixture was heated to 50 C. for 12 h, followed by addition of water and extraction with EtOAc twice. The combined organic layers were dried over Na2SO4, filtered and concentrated in vacuo. The crude product was purified by chromatography (SiO2, gradient of 5 to 20% EtOAc/Hex) to give 3C (16%) as a tan solid: 1H NMR (400 MHz, DMSO-d6) delta ppm 2.66 (s, 3 H) 7.73 (d, J=8.59 Hz, 1H) 8.08-8.17 (m, 3H) 8.25 (d, J=8.84 Hz, 2H) 13.36 (br. s., 1H); ESI-MS: m/z 376.0 (M+H)+.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 934266-82-7, 5-Bromothiazolo[5,4-b]pyridin-2-amine.
