Procedure
The product from Example 70, part d) (50 mg, 0.14 mmol) was suspended in vinylidine chloride (5 ml) with triethylamine (43 mg, 0.42 mmol). The reaction was stirred for 16 hours, diluted with dichloromethane and washed with 5% ammonia solution and then dried (MgSO4), filtered and evaporated to yield a solid which was purified by preparative thin layer chromatography using methanol/dichloromethane (3:97) as elutant to yield 12.5 mg of pure product, 1H NMR (360 MHz, CDCl3) 8.66-8.72 (2H, m), 8.35 (1H, d, J=7 Hz), 7.98 (1H, t, J=7 Hz), 7.85 (1H, t, J=7 Hz), 7.80-7.70 (2H, m), 7.28 (1H, m), 7.03 (1H, s), 5.76 (2H, s); MS (ES30) 379 [MH]+.
