Adding a certain compound to certain chemical reactions, such as: 72235-58-6, name is (4-Chloro-3-fluorophenyl)methanamine, belongs to chlorides-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 72235-58-6, Application In Synthesis of (4-Chloro-3-fluorophenyl)methanamine
A mixture of Example 477A (61.7 mg, 0.128 mmol), (4-chloro-3- fluorophenyl)methanamine (0.019 mL, 0.153 mmol), and triethylamine (0.021 mL, 0.153 mmol) in N,N-dimethylformamide (1.5 mL) was heated at 50 C for 3 hrs. After cooling, the reaction mixture was treated with brine and extracted with ethyl acetate (2x). The combined organic layers were dried over MgSO/t, filtered, and concentrated. The residue was purified by reverse- phase HPLC (see protocol in Example 112D) to provide the title compound (23.7 mg, 35%).JH NMR (400 MHz, DMSO-<) delta ppm 7.50 (dt, J = 14.5, 8.4 Hz, 2H), 7.26 - 7.15 (m, 2H), 7.11 - 7.00 (m, 2H), 6.83 (ddd, J = 8.9, 2.8, 1.1 Hz, 1H), 6.18 (t, J = 6.1 Hz, 1H), 5.74 (s, 1H), 5.02 (d, J = 4.4 Hz, 1H), 4.46 (s, 2H), 4.14 (d, J = 6.1 Hz, 2H), 4.01 (dt, J = 8.5, 3.8 Hz, 1H), 2.23 (ddd, J = 12.6, 9.4, 2.8 Hz, 1H), 2.12 - 1.98 (m, 1H), 1.95 - 1.63 (m, 8H); MS (ESI+) m/z 528.2 (M+H)+.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, (4-Chloro-3-fluorophenyl)methanamine, other downstream synthetic routes, hurry up and to see.
