Imidazole → 7-{[Tert-butyl(dimethyl)silyl]oxy}-5,6,7,8-tetrahydronaphthalen-1-amine

Participants

Reaction Steps

A mixture of Example 1F (2.33 g, 14.3 mmol), tert-butylchlorodimethylsilane (2.6 g, 17.2 mmol) and imidazole (2.9 g, 42.3 mmol) in dichloromethane (40 mL) were stirred at ambient temperature overnight. The mixture was then washed several times with water and once with brine. The organic layer was separated and dried over anhydrous sodium sulfate. Filtration and concentration afforded the title compound. 1H NMR (500 MHz, DMSO-d6) δ ppm 0.09 (s, 6H), 0.88 (s, 9H), 1.63 (m, 1H), 1.82 (m, 1H), 2.24 (m, 1H), 2.75 (m, 3H), 4.11 (m, 1H), 4.7 (br s, 2H), 6.28 (d, J=7.4 Hz, 1H), 6.42 (d, J=7.8 Hz, 1H), 6.77 (dd, J=7.8, 7.4 Hz, 1H). MS (ESI) m/z 278 (M+H)+.
