Procedure

A solution of the product of Example 31A (1.1 gm, 5.9 mmol) was dissolved in CH2Cl2/MeOH 10:1 (15 mL) and cooled to −78° C. To the solution was bubbled O3 over 20 minutes. The reaction solution was purged with N2 for a further 10 minutes and dimethyl sulfide (DMS) (3.6 gm, 59 mmol) was added and the reaction warmed to ambient temperature and stirred for a further 2 hours. The solvent was evaporated in vacuo and product purified by flash column chromatography (hexane/EtOAc 100:0 to 70:30) to collect Example 31B as an oil.
