Reaction Steps

To a solution of 9.3 ml (0.058 mol) of tetramethyl-ethylenediamine in 340 ml of THF at -78° C was added 52 ml of a 1.1M solution (0.057 mol) of s-butyl lithium in THF. The solution was then treated with a solution of 11.37 g (0.052 mol) of 2-propyl-N,N-diethylbenzamide in 75 ml of THF at -78° C. and the solution stirred for fifteen minutes and then treated with a solution of 8.3 ml of (0.104 mol) of ethyl iodide in THF. The solution was stirred for an hour and a half at -78° C. and then quenched by the addition of saturated ammonium chloride added dropwise at -78° C. The mixture was then allowed to warm to ambient temperature, diluted with diethyl ether, washed first with dilute hydrochloric acid, then with water, then with saturated sodium bicarbonate, then with brine dried and taken to dryness to give 12.91 g of crude product which was chromatographed on silica gel, eluting with 10% ethyl acetate/hexane to give 3.23 g (25%) of 2-(3-pentyl)-N,N-diethylbenzamide as a yellow oil.
