Procedure

To a solution of Compound 4 (22.6 grams, 100 mmoles) in 200 ml dry pyridine, trityl chloride (30.7 grams, 110 mmoles) was added dropwise, under argon atmosphere and the mixture was stirred overnight at room temperature. The solvent was thereafter evaporated to dryness and the residue was extracted with ethyl acetate and washed with water and brine. The organic layer was dried over sodium sulfate and the solvent was thereafter removed under reduced pressure. The resulting yellowish oily residue was purified by silica gel chromatography, using 1:2 (v:v) ethyl acetate:hexane as eluent. 41.2 grams (88% yield) of Compound 5 were obtained as an oil.
