Electric Literature of 7152-24-1, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 7152-24-1, name is 2-(Methylthio)benzimidazole belongs to imidazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below.
S1 A stirred solution of 4,5-dichloropyrimidine (206 mg, 1.38 mmol) and 2-methylthiobenzimidazole (227 mg, 1.38 mmol) in dry DMF (1.5 mL) was treated with potassium te/f-butoxide (155 mg, 1.38 mmol) then heated to 50C for 8 hours. The solution was cooled, quenched with saturated aq. ammonium chloride solution (to pH 6-7), diluted with water (30 mL) and extracted with EtOAc (40 mL). The organics were washed with water (2 x 30 mL) and brine, dried (MgS04), triturated with DCM and the liquors were chromatographed eluting with 20-50% EtOAc / PE to give 1-(5-chloropyrimidin-4-yl)-2- (methylthio)-1 /-/-benzo[d]imidazole S1 (193 mg, 50%) as a colourless gum. 1H NMR (500 MHz, CDCb) delta 9.20 (s, 1H), 9.01 (s, 1H), 7.78-7.71 (m, 1H), 7.30 (ddd, J = 8.1, 7.4, 1.1Hz, 1H), 7.22 (ddd, J = 8.4, 7.4, 1.1Hz, 1H), 7.08-7.01 (m, 1H), 2.79 (s, 3H); LCMS (method B): 2.58 min (277.0, MH+).
The synthetic route of 2-(Methylthio)benzimidazole has been constantly updated, and we look forward to future research findings.
