Adding a certain compound to certain chemical reactions, such as: 405173-97-9, name is 2-(2-Chloroethyl)-1H-benzo[d]imidazole, belongs to imidazoles-derivatives 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 405173-97-9, SDS of cas: 405173-97-9
The crude isoquinuclidine hydroiodide (106 mg, 0.40 mmol) , obtained by TMSI deprotection of 8 and triethylamine (0.17 mL, 121 mg, 1.2 mmol) in anhydrous DMF (1.5 mL) was stirred under argon at room temperature for 10 min. 2-(2′- chloroethyl ) benzimidazole (72 mg, 0.40 mmol) was then added to the above mixture and the resulting solution was allowed to stir at room temperature overnight. After the workup, the crude mixture was purified by RP-HPLC to afford a pale yellow oil (48 mg, 43% yield) . 1R NMR (300 MHz, CD3OD) delta 7.68 (2H, dd, J= 6.2, 3.2 Hz), 7.48 (2H, dd, J= 6.2, 3.1 Hz), 6.75 (1H, dd, J= 7.7, 7.7 Hz), 6.25 (1H, dd, J= 7.7, 7.7 Hz), 4.25 (1H, d, J= 5.2 Hz), 3.60 (3H, m) , 3.45 (2H, m) , 2.93 (1H, m) , 2.80 (1H, d, J= 10.5 Hz), 2.14 (1H, m) , 1.94 (1H, ddd, J= 12.6, 9.1, 2.9 Hz), 1.25 (1H, m) , 1.04 (1H, m) , 0.94 (1H, dddd, J= 7.9, 5.2, 2.6, 2.6 Hz), 0.85 (3H, t, J= 7.4 Hz); 13C NMR (75 MHz, CD3OD) delta 150.5, 140.4, 133.5, 133.5, 127.1, 127.1, 126.0, 115.1, 115.1, 59.9, 53.6, 53.3, 37.1, 30.8, 29.1, 28.9, 23.5, 11.3; m/z calcd for C18H23N3 281.19, found 281.73.
