Procedure
A solution of the compound from Example 2(ii)(6 g, 24 mmol) in DCM was stirred at 0° C. Thionyl chloride was added drop-wise and the reaction was heated at reflux for 24 hrs. The reaction was allowed to cool and the solvents removed under vacuum to afford the expected compound as a pungent crude solid. 5.9 g, 100%. The solid was used without further purification.
