A mixture of Intermediate 28a (110 mg, 0.15 mmol) and dimethylamine (2.0M in THF, 1.54 mL, 3.09 mmol) in anhydrous THF (2 mL) was stirred at 60° C. for 18 h in a sealed vial. The volatiles were concentrated in vacuo and the resultant residue was purified by MDAP (Method 7) to afford the title compound (44 mg, 43%). LCMS (Method 5): Rt 3.50 min, m/z 661 [MH+]. 1H NMR (400 MHz, DMSO): 1.19 (9H, s), 1.83-2.14 (4H, m), 2.18 (6H, s), 2.59 (2H, t, J=6.9 Hz), 3.96 (2H, t, J=6.9 Hz), 4.79-4.87 (1H, m), 5.53 (1H, t, J=4.0 Hz), 6.01 (1H, s), 6.92 (1H, d, J=8.7 Hz), 7.22-7.28 (1H, m), 7.30-7.38 (4H, m), 7.68-7.78 (3H, m), 7.90 (1H, dd, J=9.9, 0.8 Hz), 7.96 (1H, d, J=2.0 Hz), 8.15 (1H, s), 8.44 (1H, s).
