Procedure

To a pressure tube was added the product of Example 145 (150 mg, 0.23 mmol), tetra-n-butylammonium iodide (85 mg, 0.23 mmol), and 2.0 M solution of dimethylamine in THF (6 mL). The tube was sealed and heated at 65° C. for 14 h. The solution was cooled and concentrated under reduced pressure, and the crude material was purified by chromatography (silica gel, 0-20% MeOH/DCM) to provide the title compound (30 mg, 20%). 1H-NMR (CDCl3): δ 8.83 (1H, s), 7.45 (2H, d), 7.22-7.34 (5H, m), 7.11 (1H, dd), 6.71 (1H, dd), 6.63 (1H, d), 6.52 (1H, d), 5.14 (2H, s), 4.12 (2H, t), 3.70 (3H, s), 3.04 (2H, s), 2.97 (2H, q), 2.82 (2H, t), 2.40 (6H, s), 2.35 (6H, s), 1.02 (3H, t); MS(ESI): 660 (MH+).
