Reaction Steps

To the product from Example 290 and sodium triacetoxyborohydride in 9/1 dichloromethane/methanol was added excess acetaldehyde. The mixture was stirred at room temperature for 2 hours and evaporated. The residue was purified by reverse phase preparative HPLC with the AA method to provide the title compound. 1H NMR (300 MHz, DMSO-D6) δ ppm: 0.90 (t, J=7.35 Hz, 3 H) 1.09 (t, J=6.99 Hz, 3 H) 1.34 (d, J=6.99 Hz, 6 H) 1.55 (m, 2 H) 3.24 (m, 3 H) 3.38 (q, J=6.99 Hz, 2 H) 6.71 (d, J=8.82 Hz, 2 H) 6.87 (d, J=8.82 Hz, 1 H) 7.26 (d, J=8.82 Hz, 2 H) 7.63 (d, J=8.46 Hz, 1 H) 7.88 (d, J=8.46 Hz, 1 H) 8.04 (d, J=2.57 Hz, 1 H) 8.07 (d, J=2.21 Hz, 1 H) 8.17 (m, 1 H) 8.49 (d, J=1.84 Hz, 1 H) 8.58 (s, 1 H) 8.89 (d, J=8.46 Hz, 1 H) 10.13 (s, 1 H) 10.91 (s, 1 H); MS (ESI+) m/z 656/658 (M+H)+.
