Synthetic Route of 624-75-9, 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. 624-75-9, name is 2-Iodoacetonitrile belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below.
To a ice cooled stirred solution of ((benzyloxy)carbonyl)-phenylalanine (19) (0.5 g, 1.670 mmol) and TEA (0.233 mL, 1.670 mmol) in DMF (5 mL) was added 2-iodoacetonitrile (0.121 mL, 1.670 mmol) drop-wise and the resulting solution was stirred at room temperature for 12 h. The progress of the reaction was monitored by TLC. After completion, the reaction mixture was diluted with water (20 mL) and extracted with ethyl acetate (2 x 25 mL). Combined organic layer was washed with water (50 mL), saturated brine solution (50 mL) and dried over anhydrous sodium sulphate, filtered and concentrated under reduced pressure to afford brown gummy liquid of the crude product. The crude compound was purified by silica-gel flash column chromatography (eluted with ethyl-acetate/pet-ether = 2/10) to afford Cyanomethyl ((benzyloxy)carbonyl)phenylalaninate (1f) (0.5 g, 88%) as off-white solid. 1H NMR (300 MHz, DMSO-d6): delta 7.19-7.38 (m, 11H), 5.02 (s, 2H), 4.96 (d, 2H), 4.33-4.41 (m, 1H), 2.87-3.10 (m, 2H). 13C NMR (75 MHz, DMSO-d6): delta 171.4, 156.3, 136.4, 137.3, 137.2, 129.6, 128.8, 128.7, 128.2, 128.0, 127.1, 116.1, 65.9, 55.6, 49.9, 36.5 MS (ESI): 356.2 as [M+H2O] in +Ve mode and as 338.2 [M-1] in -Ve mode.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2-Iodoacetonitrile, other downstream synthetic routes, hurry up and to see.
