Reaction Conditions

Reaction Steps

Acetamide (2.95 g, 50.0 mmol) and benzyl-[2-(4-bromoacetylphenoxy)-ethyl]-carbamate (1.20 g, 3.06 mmol) were combined in a round-bottomed flask and heated to about 130° C. for about ninety minutes. The reaction mixture was then allowed to cool to room temperature, and the resulting orange solid was partitioned between ethyl acetate and water and extracted three times with ethyl acetate. The combined organic extracts were washed with brine, dried over magnesium sulfate, filtered, and concentrated in vacuo. The resulting crude solid was purified by column chromatography (silica gel; methylene chloride to 10% ethyl acetate/methylene chloride) to afford 621 mg (58% yield) of the product as a white solid. LRMS ([M+H]+)=353.3.
