Reaction Steps

To a suspension of Example 248E (125 mg, 0.359 mmol) in N,N-dimethylformamide (6 mL) was added triethylamine (0.30 mL, 2.153 mmol) and 2-chloro-N,N-dimethylacetamide (56 mg, 0.466 mmol) and the mixture was heated at 70° C. for 3 hours. After cooling, the mixture was partitioned between ethyl acetate and sodium bicarbonate and the organic phase was washed with brine and concentrated. The residue was purified by flash chromatography (5-20% methanol in 2:1 ethyl acetate/hexane) to provide the title compound. 1H NMR (400 MHz, DMSO-d6): δ 2.77-2.80 (m, 2H), 2.86 (t, J=5.65 Hz, 2H), 2.95 (s, 3H), 3.11 (s, 3H), 3.37 (q, J=2.75 Hz, 2H), 3.77 (s, 3H), 6.65-6.67 (m, 1H), 7.04-7.12 (m, 3H), 7.15-7.21 (m, 1H), 8.34 (d, J=4.88 Hz, 1H). MS (DCI/NH3) m/z 434 (M+H)+.
