Procedure
Compound 16 (1.92 g, 8.3 mmol), 4-nitrophenol (1.39 g, 10.0 mmol) and triphenylphosphine (2.62 g, 10.0 mmol) were dissolved in dry THF (100 mL) and deaerated with argon. Diisopropyl azodicarboxylate (2.0 mL, 10.0 mmol) was added in ten portions under argon and the mixture was stirred for 3 days at r.t. The mixture was evaporated to dryness and purified on silica gel (CH2Cl2), yielding 2.6 g (89%) of the title compound.
