Procedure
To a stirred solution of compound 2 (20 mg, 0.031 mmol) in THF (3 mL) under inert atmosphere was passed ammonia gas at 0° C. for 15 min; warmed to RT and stirred for 30 min. The volatiles were removed under reduced pressure and the crude was purified by triturating with n-pentane (2×5 mL) and dried under reduced pressure to afford 3 (6 mg, 35%) as a pale brown oil. 1H NMR (500 MHz, CDCl3): δ 7.73 (s, 1H), 7.70 (s, 1H), 7.64 (t, J=8.0 Hz, 1H), 7.20 (d, J=8.5 Hz, 1H), 7.11-7.08 (m, 1H), 6.95 (t, J=8.0 Hz, 1H), 6.79 (t, J=8.0 Hz, 1H), 4.65 (br s, 2H), 4.54-4.47 (m, 4H), 4.42 (q, 2H), 1.74-1.70 (m, 1H), 1.43 (t, J=7.5 Hz, 3H), 1.07-1.05 (m, 2H), 0.91-0.88 (m, 2H); LC-MS: m/z 561.7 (M+H+).
