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., 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 mm 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 mixturewas stirred under nitrogen atmosphere at room temperature for 16 h. The reaction mixture was washed successively with iN HC1 (100 mL), sat. NaHCO3 (100 mL) and brine (100 mL). The organic phase was then dried over MgSO4. Filtration and solvent removal in vacuo afforded a yellowish solid, wt: 9.3g (78%). MS: [M+1] = 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.
