Reaction Steps

A mixture of N-(4-chlorobenzyl)-7-hydroxy-2-(hydroxymethyl)-3-methylthieno[3,2-b]pyridine-6-carboxamide (100 mg, 0.276 mmol), potassium carbonate (57 mg, 0.41 mmol) and iodoacetamide (255 mg, 1.38 mmol) in DMF (1.5 mL) was stirred at 50° C. for 18 hrs. Additional iodoacetamide (255 mg) and potassium carbonate (57 mg) were added, and the reaction was stirred at the same temperature for another 12 hrs. After cooling, cold water was added, and the resulting ppt was collected by filtration after chilling in an ice bath. The collected crude solid was recrystallized from aq. ethanol to give the title compound (65 mg) as a lt. brown solid.
