2,5-Dimethylaniline → 2-Methylpentane

참여 물질

반응 단계

2,4-Dichloropyrimidine (500 mg, 3.36 mmol), 2,5-dimethylaniline (407 mg, 3.36 mmol) and triethylamine (0.51 ml, 3.69 mmol) were dissolved in EtOH (5 ml) with stirring. The reaction mixture was heated at reflux for 12 hours, cooled and evaporated onto silica (5 ml). The residue was purified by column chromatography and eluted with EtOAc (30%): isohexane to give the title product as a waxy solid on evaporation (514 mg, 66%). NMR (300 MHz): 2.1 (s, 3H), 2.27 (s, 3H), 6.42 (d. 1H), 6.99 (d, 1H), 7.08 (s, 1H). 7.18 (d, 1H), 8.03 (d, 1H), 9.45 (s, 1H); m/z: (ES+) 234.3 (MH+).
