89976-56-7,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 downstream synthesis route of the compound 89976-56-7
89976-56-7, A solution of 2,4-dimethoxybenzene-1-sulfonyl chloride (0.0799 g, 0.337 mmol) and 5-methylbenzo[d]isoxazol-3-amine I60 (0.050 g, 0.34 mmol) in pyridine (1 ml.) was irradiated in the microwave at 110 C for 2 hours. The resultant mixture was loaded onto silica gel and the product purified by column chromatography (12 g S1O2 cartridge, 0-45% EtOAc in petroleum benzine 40-60 C) [205] to yield the title compound (55.0 mg, 42% yield) as a white solid. NMR (400 MHz, CDCb) d 7.86 – 7.82 (m,1H), 7.72 (d, J = 8.81Hz, 1H), 7.37 – 7.28 (m, 2H), 6.49 (d, J = 2.26 Hz, 1H), 6.43 (dd, J = 2.29, 8.82 Hz, 1H), 3.96 (s, 3H), 3.80 (s, 3H), 2.47 (s, 3H). LCMS-A: rt 5.66 min, m/z 348.8 [M+H]+, 347.1 [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 5-Methylbenzo[d]isoxazol-3-amine.
