Reaction Steps

A mixture of the title compound from Example 250 (0.26 grams), sodium hydride (0.08 grams, 60% in mineral oil), methyl thioglycolate (0.19 mL) and anhydrous DMF (15 mL) was stirred while being irradiated with a 200 W lamp for 16 hours. The mixture was diluted with MeOH, concentrated in vacuo, diluted with CH2Cl2 and water, and washed with 1N aqueous NaOH and brine. The organic phase was dried over anhydrous MgSO4 and concentrated in vacuo and the residue purified by preparative plate chromatography (silica gel) using 3% MeOH-CH2 Cl2 to afford the title compound (0.05 grams, 15%, MH+ 534).
