Electric Literature of 10386-27-3, 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. 10386-27-3, name is 2-Bromoisonicotinonitrile, molecular formula is C6H3BrN2, The 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.
StepD: (4S)-tert-Butyl 4-((l-(2-chlorophenyl)-2-(3,3-difluorocyclobutylamino) -2-oxoethyl){3- fluorophenyl)carbamoyl)-3-(4-cyanopyridin-2-yl)-2-oxoimidazolidine-l-carboxylate. To a 25 mL flask charged with 1,4-dioxane (4.5 mL) were added(4S)-tert-butyl4-((l-(2-chlorophenyI)- 2-(33-difluoro cyclo butylamino)-2-oxoethyl)(3-fiuoro -phenyl)carbamoyl)-2-oxoimidazolidine- 1- carboxylate (250 mg, 0.43 mmol), 2-bromoisonicotinonitrile (122 mg 0.65 mmol), CS2CO3 (281 mg, 0.862 mmol), Xant-Phos (25 mg 0.043 mmol) and Pd2(dba)3 (40 mg, 0.043 mmol). The mixture was degassed and refilled with nitrogen, and then heated to 100 °C for 3 hr. The resulting mixture was cooled and filtered. The filtrate was concentrated in vacuo and the residue was purified by a standard method to give both epimers. The epimers were further separated by a standard method to give the desired product. ‘HNMR (400 MHz, CDC13): delta 8.58 (s, 1H), 8.48 (t, J= 5.9 Hz, 1H), 7.71 (d, J= 8.4 Hz, 1H),7.37 – 7.16 (m, 4H), 7.15 – 6.76 (m, 4H), 6.56 – 6.31 (m, 2H), 4.95 – 4.75 (m, 1H), 4.31 (s, 1H), 3.86 (dd,J= 10.8, 5.1 Hz, 1H), 3.66 (m, 1H), 2.99 (m, 2H),2.61 -2.27 (m, 2H), 1.56 (s,9H).MS : 683(M + 1)+.
While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 10386-27-3, 2-Bromoisonicotinonitrile.
