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. 51628-12-7, name is 2-(4-Iodophenyl)acetonitrile belongs to iodides-buliding-blocks compound, it is a common compound, a new synthetic route is introduced below. COA of Formula: C8H6IN
To a solution of 4-iodophenylacetonitrile (6.88 g, 28.3 mmol, 1 eq.) and bis-(2-chloro-ethyl)-carbamic acid tert-butyl ester (7.2 g, 30 mmol, 1.05 eq.) in DMSO (100 mL) under argon (Ar) was added NaNH2 (2.46 g, 60 mmol, 2 eq.) in portions over 15 min. The reaction was stirred at room temperature for 0.5 h, then poured onto ice (200 g), diluted with EtOAc (250 mL) and stirred for 1 h. The organic layer was separated and the aqueous layer was washed repeatedly with EtOAc until colorless. The combined organic extracts were dried over anhydrous Na2SO4, filtered and concentrated by rotary evaporation to afford an orange oil which was purified by flash column chromatography by eluding with 7-12% EtOAc/hexanes to yield 4-cyano-4-(4-iodo-phenyl)-piperidine-1-carboxylic acid tert-butyl ester as a pale orange oil/solid (8.28 g, 18.96 mmol, 67%). 1H NMR (300 MHz, CDCl3): delta 7.82 (dd, 2H), 7.26 (dd, 2H), 4.38 (br. s, 2H), 4.28 (br. t, 2H), 2.15 (m, 2H), 2.0 (td, 2H), 1.59 (s, 9H).
The synthetic route of 51628-12-7 has been constantly updated, and we look forward to future research findings.
