Adding a certain compound to certain chemical reactions, such as: 17417-09-3, name is 2-Fluoro-5-nitrobenzonitrile, belongs to nitriles-buliding-blocks compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 17417-09-3, Computed Properties of C7H3FN2O2
Part A: Preparation of 2-fluoro-5-aminobenzonitrile. To a solution of 2-fluoro-5-nitrobenzonitrile(2.0 g, 12 mmol) in ethyl acetate(50 mL) was added stannous chloride(27.0 g, 120 mmol). The reaction-mixture was stirred at reflux 1.5 h, then cooled to room temperature. Partitioned between ethyl acetate(150 mL) and saturated sodium bicarbonate(150 mL). Organic phase was separated and washed with water(5×75 mL), brine(75 mL); dried over sodium sulfate(anhy.); filtered and concentrated to give 2-fluoro-5-aminobenzonitrile (1.4 g) as pure compound.
