Reaction Steps

To a solution of Example 165 (20 mg, 0.05 mmol) in N,N-dimethylformamide (1 mL) was added acetic acid (4 mg, 0.07 mmol) and triethylamine (0.1 mL) at room temperature. 1-Ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride (11 mg, 0.07 mmol) and N-hydroxybenzotriazole (10 mg, 0.07 mmol) were added and the mixture was stirred overnight. Purification by HPLC (Zorbax XDB C-18 (32) using a gradient of 5-40% acetonitrile/water (containing 0.1% trifluoroacetic acid) afforded the title compound. 1H NMR (400 MHz, DMSO-d6): δ 1.57-1.93 (m, 5H), 1.96 (s, 3H), 2.28 (d, J=13.73 Hz, 2H), 2.80 (d, J=3.97 Hz, 3H), 2.87-3.01 (m, 2H), 3.02-3.22 (m, 5H), 3.52 (d, J=11.60 Hz, 2H), 3.77 (d, J=13.12 Hz, 2H), 4.34 (d, J=12.82 Hz, 2H), 6.10 (s, 1H), 6.61 (d, J=9.16 Hz, 1H), 7.11-7.18 (m, 1H), 7.56 (d, J=9.16 Hz, 1H), 8.23 (d, J=5.19 Hz, 1H). LCMS: 481 (M+H)+.
