Procedure

To a stirred, ice cold solution of 4-(2-tetrahydropyranyloxy)nonylamine (7.29 g., 0.03 mole) in pyridine (40 ml.) is added methanesulfonylchloride (3.42 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 six hours, poured into ice water (200 ml.) and extracted with ether (2× 100 ml.). The ether is washed with ice cold 5% hydrochloric acid (2× 20 ml.), with brine (2× 25 ml.), and then dried over sodium sulfate. Evaporation in vacuo affords N-[4-(2-tetrahydropyranyloxy)nonyl]methanesulfonamide as a pale yellow liquid.
