N-(4-cyanophenyl)acetamide → HCID 69058617, compound

Participants

Reaction Steps

9 g (54.1 mmol) of N-(4-cyanophenyl)acetamide are dissolved in 100 ml of THF. The mixture is cooled to 0° C. before the dropwise addition of 51 ml of a 1.6 N solution in hexane of nBuLi (1.5 eq.). The solution is left for one hour to return to ambient temperature and is then cooled to 0° C. before the dropwise addition of 9.9 ml of 1-chloro-4-iodobutane (81 mmol). The reaction mixture is stirred at ambient temperature for 18 h and then hydrolysed with a saturated aqueous solution of ammonium chloride (100 ml) and extracted with ethyl acetate. The organic phases are combined, dried over magnesium sulphate and concentrated. Purification by chromatography on silica (eluant: petroleum ether/ethyl acetate: 1/1) yields a yellow oil containing the expected product.
