Combine 4-(5-Oxo-5,6,7,8-tetrahydro-naphthalen-2-yloxy)-benzonitrile (5.34, 20.3 mmol), t-butyl alcohol (100 ml), and KOH (5.7 g, 101.5 mmol). After the reaction stirs for 72 hours at room temperature, concentrate under reduced pressure and then add ethyl acetate. Wash the organic phase with water, a brine solution, and then dry the organic layer over Na2SO4. Flash chromatograph using 2/1 CH2Cl2/ethyl acetate eluent to afford 5.20 g, 18.5 mmol (91% yield) of the title compound: 1H NMR (500 MHz, CDCl3); 2.1-2.2 (2H, m), 2.6-2.7 (2H, m), 2.9-3.0 (2H, m), 5.6-6.2 (2H, br m); 6.85 (1H, s), 6.9-7.0 (1H, m), 7.05-7.15 (2H, m), 7.8-7.9 (2H, m) 8.05-8.10 (1H, m); MS m/z 284 (M+3).
