Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 7149-75-9, name is 4-Chloro-3-methylaniline, This compound has unique chemical properties. The synthetic route is as follows., Recommanded Product: 4-Chloro-3-methylaniline
Step 2 (0404) To a mixture of 1-(3-formylbenzyl)azetidine-3-carboxylic acid methyl ester (330 mg), 4-chloro-3-methylphenylamine (243 mg) and methanol (8 mL) was added decaborane (90 mg), and the mixture was stirred at room temperature for 2 hours. After the mixture was diluted with ethyl acetate, to the resulting mixture was added aminopropyl silica gel powder (3 g). The resulting mixture was filtered and the filtrate was concentrated under reduced pressure. The residue was purified by aminopropyl silica gel column chromatography (eluent: 20percent-50percent ethyl acetate/hexane, gradient elution) to give the title compound (450 mg). The structural formula was illustrated in Table 1. [table-us-00001-en] Reference Example Structural formula 1-1 (0405) The physical data of Reference Example 1-1 was shown below. Reference Example 1-1 (0406) MS (ESI, m/z): 359(M+H)+
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 7149-75-9.
