Procedure
To a solution of XIV (4.4 g, 11.8 mmol) in pyridine (30 ml) was added p-nitrophenyl trifluoroacetate (3.22 g, 13.7mmol). After stirring for 24 h at room temperature, the reaction mixture was treated in the same manner as described for the preparation of X. An oil obtained gave a single spot on TLC; yield 5.67 g (98%), Rf1 0.60.
