Acetic Anhydride → N-{4-[(Oxan-2-yl)oxy]nonyl}acetamide

Participants

Reaction Steps

To a stirred, ice cold solution of 4-(2-tetrahydropyranyloxy)nonylamine (7.29 g., 0.03 mole) in pyridine (40 ml.) is added acetic anhydride (3.06 g., 0.03 mole) at such a rate as to maintain the reaction temperature at 5°-10°C. The reaction is then allowed to stand at room temperature for 6 hours, poured into ice water (200 ml.) and extracted with ether (2 × 100 ml.). The ether is extracted with ice cold 5% hydrochloric acid (2 × 20 ml.), washed with brine (2 × 25 ml.), then dried over sodium sulfate. Evaporation in vacuo affords the subject compound as a pale yellow oil.
