A variety of substituted aryl amines were transformed into aryl azides using t-BuONO and moist NaN3 in t-BuOH in good to excellent yields. Smooth transformation was observed with anilines, having electron withdrawing and donating groups. Both acid- and base-sensitive groups survived the reaction conditions.
