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.

Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps,and cheap raw materials. 10386-27-3, name is 2-Bromoisonicotinonitrile. A new synthetic method of this compound is introduced below., Application In Synthesis of 2-Bromoisonicotinonitrile

To a solution of 2-(pyridin-2-yl)-4,5,6,7-tetrahydrooxazolo[4,5-c] pyridine (I- 23.4) (40 mg, 0.2 mmol) in DMF (2 mL) was added 2-bromoisonicotinonitrile (54 mg, 0.3 mmol), DIEA (52 mg, 0.4 mmol). The mixture was heated to 1000C and stirred for 16 h. The mixture was cooled to room temperature and poured into water. The mixture was extracted with EtOAc. The combined organic phase was dried over anhydrous Na2SO4 and concentrated. The residue was purified by preparative TLC to afford 2-(2- (pyridin-2-yl)-6,7-dihydrooxazolo[4,5-c]pyridin-5(4H)-yl)isonicotinonitrile (10 mg, 17percent) as a yellow solid. 1H NMR (400 MHz, CDCl3): delta 8.67 (d, IH), 8.25 (d, IH), 8.03 (d, IH), 7.75 (t, IH), 7.30 (t, IH), 6.81 (s, IH), 6.75 (d, IH), 4.52 (s, 2H), 4.07 (t, 2H), 2.91 (t, 2H); LC/MS: m/e = 304 (M+H)+.
