    • note
    • 19 (5.0 g) in dry toluene (22 mL) was stirred at room temperature under an argon atmosphere for 30 min. Thionyl chloride (22 mL) was added, and the suspension was refluxed for 24 h with vigorous stirring, then cooled and filtered. The resin was washed with toluene (2 × 25 mL) and ethyl ether (2 × 25 mL). If stored at -18 °C under argon, it could be used for 2-3 months without a significant loss of activity.
