Reaction Steps

2-Iodopropane (6.5 g, 0.038 mol) was added to a well-stirred mixture of benzofuran-6-acetonitrile (3.0 g, 0.019 mol), tetrabutylammonium hydrogen sulphate (6.5 g, 0.019 mol), sodium hydroxide (47% w/w, 20 cm3, 0.037 mol), water (10 cm3) and dichloromethane (50 cm3), and the mixture was refluxed for 6 hr. with good stirring. The organic layer was washed with water, dried (Na2SO4), filtered and the solvent was removed. Toluene (15 cm3) was added to the residue, the mixture was filtered, and the solvent was removed. The residue was chromatographed on silica using toluene as eluant, to give α-isopropylbenzofuran-6-acetonitrile (1.62, 0.0081 mol, 42.6%) as an oil. (Found: C, 79.32; H, 6.22; N, 6.55. C13H13NO requires C, 78.36, H, 6.58; N, 7.03%) t.l.c./silica/toluene RF 0.38.
