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. 20781-20-8, name is (2,4-Dimethoxyphenyl)methanamine, This compound has unique chemical properties. The synthetic route is as follows., COA of Formula: C9H13NO2
To a solution of 5-fluoro-2-nitrobenzoic acid (6.6g, 35.66 mmol) in dichloromethane (100 mL) were added DIPEA (9.22 g, 71.3 mmol), HOBt (6.0 g, 39.2 mmol) and EDCI (10.2 g, 53.5 mmol). After about 15 min stirring, to the reaction mixture was added a solution of 2,4-dimethoxybenzyl amine (5.96 g, 35.66 mmol) in dichloromethane (50 mL) dropwise under nitrogen atmosphere. The resulting mixture was stirred under nitrogen atmosphere at room temperature for 16 h. The reaction mixture was washed successively with 1N HC1 (100 mL), sat. NaHCCb (100 mL) and brine (100 mL). The organic phase was then dried over MgS04. Filtration and solvent removal in vacuo afforded a yellowish solid, wt: 9.3g (78%). MS: [M+l] = 335.
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 20781-20-8.
