Procedure

To the product from Example 290 and sodium triacetoxyborohydride in 9/1 dichloromethane/methanol was added excess formaldehyde (37% in water). 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: 0.88 (t, J=7.35 Hz, 3 H) 1.34 (d, J=6.99 Hz, 6 H) 1.54 (m, 2 H) 2.93 (s, 3 H) 3.25 (m, 3 H) 6.75 (d, J=9.19 Hz, 2 H) 6.85 (d, J=7.72 Hz, 1 H) 7.27 (d, J=8.82 Hz, 2 H) 7.63 (d, J=8.46 Hz, 1 H) 7.87 (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=2.21 Hz, 1 H) 8.58 (s, 1 H) 8.88 (d, J=8.82 Hz, 1 H) 10.13 (s, 1 H) 10.91 (s, 1 H); MS (ESI+) m/z 642/644 (M+H)+.
