Procedure

A solution of Example 185 (1 g, 2.11 mmol) in 25 mL of dichloromethane was cooled to to 0° C., treated with 1,8-diazabicyclo[5.4.0]undec-7-ene (1.7 mL, 11.2 mmol) and diphenylphosphoryl azide (2.3 mL, 10.9 mmol), allowed to warm to room temp, stirred for 16 h, and concentrated onto silica gel. The crude material was chromatographed on silica gel with hexane, hexane/dichloromethane (1:1), followed by dichloromethane, and methanol/dichloromethane (1:99) to afford the title compound (610 mg, 59% yield). 1H NMR (300 MHz, DMSO-d6) δ ppm 0.39 (td, J=12.7, 3.3 Hz, 1 H), 0.72 (s, 9 H), 0.81 (td, J=13.1, 4.6 Hz, 1 H), 1.57 (s, 3 H), 2.05 (m, 1 H), 2.22 (td, J=12.6, 4.6 Hz, 1 H), 4.56 (s, 2 H), 7.29 (m, J=8.6, 8.6 Hz, 1 H), 7.54 (s, 1 H), 7.74 (m, J=4.0 Hz, 2 H), 8.13 (d, J=7.7 Hz, 1 H), 14.09 (s, 1 H); MS (APCI+) m/z 498 (M+H)+.
