Reaction Steps

A mixture of Example 282A (80.0 mg, 0.182 mmol), 2-chloro-N,N-dimethylacetamide (0.021 mL, 0.209 mmol), and triethylamine (0.127 mL, 0.908 mmol) in N,N-dimethylformamide (2 mL) was heated at 75° C. for 4 hours. The mixture was treated with water and brine and extracted with ethyl acetate (twice). The combined organic layers were washed with brine, dried over magnesium sulfate, filtered, concentrated, and purified by HPLC (same protocol as Example 221). The trifluoroacetic acid salt was flushed through an SCX column eluting with 2M ammonia in methanol to give the free base of the title compound. 1H NMR (400 MHz, Pyridine-d5) δ 2.58-3.06 (m, 13H), 3.31 (d, J=5.4 Hz, 2H), 3.39-3.44 (m, 1H), 3.71 (s, 3H), 6.43 (bs, 1H), 6.48 (bs, 1H), 7.12 (dd, J=9.1, 4.5 Hz, 1H), 7.27-7.36 (m, 1H), 7.50 (d, J=8.8 Hz, 1H), 8.51 (d, J=2.6 Hz, 1H), 13.13 (bs, 1H). MS (ESI+) m/z 453.2 (M+H)+.
