Reaktionsschritte

To a slurry containing 5.0 g (33 mmol) of 2-methyl-3-nitrophenol, 9.4 g (65.2 mmol) of (2-chloroethyl)dimethylamine hydrochloride, 9.0 g (65.3 mmol) of K2CO3, and 100 mL of H2O was added 100 mL of butanol and the reaction mixture was heated at 80° C. for 13 h. The reaction mixture was extracted with EtOAc and the combined organic layers were dried over MgSO4 and filtered. The solvents were removed under reduced pressure and the residue was subjected to silica gel chromatography to give 7.4 g (100%) of dimethyl{2-[(2-methyl-3-nitrophenyl)oxy]ethyl}amine as a brown oil. 1HNMR (400 MHz, DMSO-d6) δ 7.29-7.42 (m, 3H), 4.11 (t, J=5.6 Hz, 2H), 2.66 (t, J=5.6 Hz, 2H), 2.22 (s, 3H), 2.20 (s, 6H). MS (ESI+) m/z 225 [M+H].
