Reaction Steps

To a solution of the product from Example 10B (90 mg, 0.517 mmol) and the product from Example 5I (122 mg, 0.569 mmol) in acetic acid (1 mL) was heated at 130° C. for 1 hour. The mixture was then allowed to cool to room temperature, the resulting solid collected and washed with methanol, then dissolved 50 mg of the material in dioxane (2 mL) and added hydrochloric acid followed by removal of the solvent under vacuum to provide the title compound as a hydrochloride salt. 1H NMR (300 MHz, DMSO-D6) δ ppm: 2.37 (s, 3H), 2.74 (s, 3H), 7.18 (m, 5H), 7.24 (m, 1H), 7.37 (m, 2H), 7.81 (d, J=8.5 Hz, 1H), 8.80 (s, 1H), 8.99 (d, J=8.5 Hz, 1H), 11.82 (bs, 1H); MS (ESI)+ m/z 359 (M+H)+.
