Reaction Steps

A 1l reactor was charged with 57 g (0.5 mole) of azacycloheptane-2-one, 125 g (0.5 mole) of dodecyl bromide, 182 g of toluene, 3.2 g (2 mole %) of crystalline tetrabutylammonium bromide (TBAB) and 60 g (1.5 moles) of flaky sodium hydroxide. This heterogeneous mixture was stirred at 50° C. for 10 hours. The same aftertreatment as in Example 1 was repeated, giving 133.5 g of 1-dodecylazacycloheptane-2-one (yield of 95.0%) and 0.7 g of dodecyl ether (yield of 0.8%)
