The important role of 53312-80-4

At the same time, in my other blogs, there are other synthetic methods of this type of compound, 4-Amino-2-fluorobenzonitrile, and friends who are interested can also refer to it.

Application of 53312-80-4, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 53312-80-4 name is 4-Amino-2-fluorobenzonitrile, This compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

Sodium cyanide (0.74 g, 15 mmol) was added to a mixture of 4-amino-2- fiuorobenzonitrile (1.36 g, 10 mmol) and cyclopentanone (1.26 g, 15 mmol) in 90% acetic acid (10 ml). The reaction mixture was stirred at room temperature for 3 hours and then the medium was hearted to 80 0C and stirred for an additional 5 hours. The medium was washed with water and extracted with ethyl acetate. The organic layer was dried over magnesium sulfate, concentrated and chromatographed (dichloromethane:acetone, 97:3) to yield 4-(l-cyanocyclopentylamino)-2-fluorobenzonitrile (54b) (2.07 g, 9.03 mmol, 90%) as a yellow solid. 1H NMR (CDCl3, 400 MHz) delta 1.69-1.91 (m, 4H), 2.13-2.18 (m, EPO 2H), 2.37-2.42 (m, 2H), 5.08 (bs, IH), 6.54-6.62 (m, 2H), 7.39 (t, J= 7.3 Hz, IH); 13C NMR (CDCl3, 100 MHz) delta 23.7, 39.8, 56.8, 89.6 (d, J = 15.8 Hz), 101.2 (d, J= 23.8 Hz), 110.9, 115.2, 120.8, 134.1 (d, /= 2.4 Hz), 150.3 (d, J= 11.2 Hz), 164.5 (d, J= 254.1 Hz).
