Reaction Steps

A stirred suspension of dry ethylamine hydrochloride (3.26 g, 0.04 mol) in toluene, under nitrogen, was cooled in an ice bath and treated during 40 minutes with 20 ml of a 2.0M solution of trimethylaluminum in hexane. The mixture was kept at 0° for 10 minutes and at ambient temperature for 2.5 hours. A portion of the resulting solution (46.8 ml) was added, under nitrogen, during 15 minutes to a solution of the product from Step I (2.0 g, 0.016 mol) in toluene (100 ml). This mixture was warmed at 80° C. for 3 hours, cooled and added continuously to dilute HCl. The product was extracted with ethyl acetate. The extracts were dried (MgSO4) and concentrated to give 2.27 g of N-ethyl-6-hydroxyheptanamide.
