Procedure

4,4'-Dimethoxytrityl chloride (685 mg, 2.02 mmol) was added to a solution of Compound C5 (825 mg, 1.69 mmol) in anhydrous pyridine (4 ml) and the mixture was stirred at room temperature for 3 hours. After cooling, aqueous 50% pyridine was added to decompose an excess of the reagent, and the mixture was extracted with ether containing a small amount of chloroform. The organic layer was washed with aqueous sodium bicarbonate and dried over magnesium sulfate. The organic solvents were evaporated, the remaining pyridine was removed as the toluene azeotrope and the residue was subjected to silica gel chromatography [eluant; chloroform-ethyl acetate-triethylamine (80:20:1)] to give 1.280 g of the desired compound, C6 (yield 96%).
