Reaction Steps

To a solution of 4-[3-(1-adamantyl)-4-methoxymethoxyphenyl]benzaldehyde (6.88 g, 18.30 mmol) in 200 mL of THF:isopropanol (1:1) was a added 30 mL of6 N HCl at room temperature. After 20 hours 30 mL of 12 N HCl was added. After 57 hours starting material was still present, 60 mL of additional 12 N HCl was added and stirred for 16 hours. The resulting mixture was diluted with water and extracted with ether (2×200 mL). The combined organics were washed with water (150 mL), brine (100 mL), dried over anhydrous magnesium sulfate, filtered and evaporated to give 6.00 g (99%) of 4-[3-(1-adamantyl)-4-hydroxyphenyl]benzaldehyde as a solid. 1H NMR (300 MHz; DMSO-d6): δ 1.72 (brs, 6H), 2.00–2.20 (m, 9H), 6.88 (d, J=8.7 Hz, 1H), 7.36–7.48 (m, 2H), 7.78 (d, J=8.1 Hz, 2H), 7.90 (d, J=8.1 Hz, 2H), 9.67 (s, 1H), 9.98 (s, 1H).
