実験手順

A solution of 1-(2-bromoethoxy)-2-methoxybenzene (7d) (7.7 g, 33 mmol) in a 33% solution of methylamine in ethanol was heated at 80° C. in a sealed tube for 16 h. After cooling to room temperature, the solvents were evaporated in vacuo. A 2N aqueous solution of sodium hydroxide was added to the remaining oil and the resulting slurry was extracted with ethyl acetate (2×250 mL). The collected organic phases were dried (Na2SO4) and the solvents evaporated in vacuo giving 5.9 g (98%) of the title compound as an oil: 1H NMR (CDCl3) δ 1.85 (broad s, 1H), 2.50 (s, 3H), 3.00 (t, 2H), 3.85 (s, 3H), 4.10 (t, 2H), 6.85-6.95 (m, 4H).
