Procedure

The compound of Example 1I is dissolved in pyridine and cooled in an ice bath; methylthiomethyl chloride (1.2 eq) is added, and the mixture is warmed to ambient temperature, then heated to 90° C. overnight. The solvents are removed in vacuo; the residue is partitioned between aqueous phosphoric acid (1N) and ethyl acetate. The organic extract is washed with brine, dried (Na2SO4), filtered, and concentrated in vacuo. The crude material is purified by column chromatography.
