Reaction Steps

To the resultant compound from Example 20 (0.264 g, 0.932 mmol) in DMF (4 ml) was added tert-butyldimethylsilyl chloride (0.300 g, 1.99 mmol) and imidazole (0.269 g, 3.95 mmol). The mixture was stirred at room temperature for 12 hours, poured into ethyl acetate and washed sequentially with 0.5M H3PO4, saturated NaHCO3 solution and brine, then dried over Na2SO4 and evaporated to afford 0.355 g (96%) of the desired compound. Mass spectrum: (M+H)+ =398.
