Reaction Steps

To a solution of 4.74 mL (0.031 mol) of tetramethylethylenediamine in 300 mL of THF (passed through alumina prior to use) was added 5.8 g (0.03 mol) of 2-ethyl-N,N-diethyl-benzamide. The solution was cooled to -78° C. and treated with 34.9 mL (0.031 mol) of a 0.9M solution of butyl lithium in cyclohexane. When addition was completed, the mixture was stirred for twenty minutes and then treated with a solution of 3.2 mL (0.04 mol) of ethyliodide while maintaining the temperature at -78° C. The temperature was then allowed to rise to ambient temperature and the mixture was stirred for about sixteen hours and then poured into water. The resulting oil was separated and chromatographed on silica gel, eluting with 10% ethyl acetate/hexane to give 2.86 g (43%) of 2-sec-butyl-N,N-diethylbenzamide as a yellow oil.
