실험 절차

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--Choro-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 cetate in hexane as eluent to give a mixture of two isomers as a yellow glass form and oth having a M+ of 365 from GC/Ms. 1H NMR (CDCl3) δ6.8 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.
