실험 절차
To the subtitle product of step i) (5.0 g) in dichloroethane (25 ml) was added aza-bis-isobutyronitrile (25 mg) and the mixture heated to 60° C. Sulfuryl chloride (3.67 g) was then added and the reaction heated at 75° C. for 4 h. The same amount of aza-bis-isobutyronitrile (4×25 mg) and sulfuryl chloride (4×3.36 g) was added for 4 days on each day interval. The solvent was evaporated to give a yellow oil which was distilled under reduced pressure to yield the subtitle compound as a yellow oil. Yield 5.8 g.
