실험 절차

To a mixture of Example 168C (0.10 g, 0.325 mmol) in 2 mL of water was added 1.5 mL 6 M HCl. The resulting solution was cooled to 0° C. and NaNO2 (0.034 g, 0.488 mmol), dissolved in 1 mL water, was added dropwise. The resulting mixture was stirred for 30 minutes at 0° C. and subsequently heated to 90° C. for one hour. After cooling, contents were filtered and the precipitate was washed with 10 mL water and dried under reduced pressure to provide the product in 47% yield as a brown solid in HCl salt form, which was used without further purification. 1H NMR (CD3OD, 300 MHz) δ 8.10 (d, J=9 Hz, 1H), 7.82 (d, J=3 Hz, 1H), 7.60 (dd, J=3, 9 Hz, 1H), 3.89-3.76 (m, 2H), 3.58-3.53 (m, 1H) 3.42-3.23 (m, 4H), 2.38-2.30 (m, 1H), 2.16-2.06 (m, 2H), 1.83-1.75 (m, 1H), 1.51 (d, J=6 Hz, 3H). MS (ESI) [M]+ at 336.
