Reaction Conditions

Reaction Steps

DMF (7.5 mL) was added to (5-(3-chloropropoxy)-2-nitrophenyl)methanol (635 mg, 0.00258 moles) and sodium azide (252 mg, 0.00387 moles) in a flask, and the resulting mixture was heated to 70° C. and stirred overnight. The reaction was diluted in ethyl acetate (100 mL) and washed twice with water (75 mL each) and once with brine (75 mL). The organic layer was dried with anhydrous magnesium sulfate, which was filtered out. The filtrate was concentrated on a rotary evaporator and dried in vacuo overnight to yield (5-(3-azidopropoxy)-2-nitrophenyl)methanol as a yellow solid (yield 88%).
