Reaction Steps

(2-bromoethoxy)(tert-butyl)dimethylsilane (20 g, 84 mmol) was added to a solution of (4-methoxyphenyl) methanamine (11.47 g, 84 mmol) in acetonitrile (200 mL) followed by K2CO3 (57.8 g, 418 mmol), and the mixture was stirred at 80° C. for 16 h. Insoluble solids were filtered off, filtrate was concentrated and partitioned between ethyl acetate and water. Organic layer was separated, washed with brine, dried over sodium sulphate and filtered. The filtrate was concentrated in vacuo and purified by flash chromatography using 30% ethyl acetate in hexane to afford title compound (19 g, 77%) as an oil. 1H NMR (300 MHz, DMSO-d6): δ 7.22 (d, J=8.4 Hz, 2H), 6.82 (d, J=8.7 Hz, 2H), 3.77 (s, 3H), 3.62 (m, 4H), 2.56 (t, J=5.7 Hz, 2H), 2.5 (m, 1H), 0.85 (s, 9H), 0.02 (s, 6H).
