DPPA (11 mls, 50.9 mmol) was added to a stirred mixture of the product from Preparation 78 (8.9 g, 46.3 mmol), triethylamine (10.1 mls, 72.7 mmol) and tert-BuOH (75 mls). The mixture was heated at 90° C. for 43 h. When cool, the tert-BuOH was removed by evaporation and the resulting oily residue treated with saturated K2CO(120 ml) and then extracted with EtOAc (2×100 mls). The combined organic extracts were then evaporated under reduced pressure to give a brown solid which was purified by column chromatography using DCM:MeOH (98:2) as eluant to provide the title product (5.8 g, 148%);
