Participants

Reaction Steps

To a solution of 4-(adamantan-1-ylmethoxy)-3-(2-methoxypyridin-3-yl)benzonitrile (1.15 g, 3.07 mmol) in dimethylsulfoxide (25 mL) and methylene chloride (25 mL) was added potassium carbonate (0.85 g, 6.15 mmol) followed by addition of 35% hydrogen peroxide aqueous solution (5.30 mL, 61.60 mmol) dropwise. The mixture was stirred at ambient temperature for 4 h, the volatiles were removed by evaporation in vacuo. The residue was diluted with water (100 mL). The precipitate was collected by filtration and washed with water to give the title compound as a colorless solid (0.97 g, 80%): 1H NMR (300 MHz, CDCl3) δ 8.18-8.15 (m, 1H), 7.84-7.79 (m, 1H), 7.71-7.69 (m, 1H), 7.54-7.50 (m, 1H), 6.95-6.91 (m, 2H), 5.85 (br s, 2H), 3.87 (s, 3H), 3.49 (s, 2H), 1.89 (br s, 3H), 1.68-1.37 (m, 12H); MS (ES+) m/z: 393.2 (M+1).
