Participants

Reaction Steps

A mixture of Example 161B (61 mg, 0.15 mmol), 2 mL of acetic acid, 0.15 mL of hydrogen peroxide (30% solution in water) in 0.5 mL of N,N-dimethylformamide was stirred at room temperature for 2 h. Water was added, the resulting precipitate was then filtered. The solid was triturated with methanol to provide the titled compound as a beige solid (44 mg, 70%). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.30 (t, J=7.1 Hz, 3H), 4.43-4.53 (m, 4H), 7.05 (s, 1H), 7.29 (bs, 2H), 7.43 (d, J=8.6 Hz, 2H), 7.46-7.55 (m, 3H), 7.63-7.72 (m, 4H), 9.08 (t, J=6.4 Hz, 1H). MS (ESI+) m/e=421 (M+H)+.
