3-Pentanol → 2-[6-(1-Ethyl-propoxy)-2,5-dimethylpyrimidin-4-yl]-2-(2,4,6-trimethylphenyl)-propionitrile

Participants

Reaction Steps

To a solution of 3-pentanol (140 mg, 1.59 mmol) in 2 ml of dry THF was added sodium hydride (60% in oil, 38 mg) and the mixture was stirred at room temperature for 5 minutes. 2-(6-Chloro-2,5-dimethylpyrimidin-4-yl)-2-(2,4,6-trimethylphenyl)-propionitrile (100 mg, 0.319 mmol) was added to the reaction mixture, and the resulting mixture was heated at reflux for 4 hours. The mixture was quenched with water and extracted with ethyl acetate. The organic layer was separated, dried and concentrated to give a brown oil (170 mg). The residue was purified through chromatotron using 20% ethyl acetate in hexane as eluent to give a mixture of two isomers as a yellow glass form and both having a M+ of 365 from GC/Ms. 1H NMR (CDCl3) δ 6.8 and 6.76 (s, 2H), 4.08 and 3.96 (m, 1H), 3.25 and 3.22 (s, 3H), 2.36 and 2.30 (s, 3H), 2.21, 2.20 and 2.06 (s, total of 9H), 1.5-1.7 (m, 4H), 1.04 (s, 3H), 0.96 and 0.90 (t, 3H) ppm.
