Procedure

A mixture of 4-n-propylbenzoic acid (10.0 g), 1-hydroxybenzotriazole hydrate (8.20 g), 1-(3-N,N-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (21.5 g) and dichloromethane (1000 ml) was treated dropwise with triethylamine (42.6 ml) and N,O-dimethylhydroxylamine hydrochloride (6.6 g). The mixture was stirred overnight at room temperature and then treated with water (700 ml). The organic layer was separated, washed with 2N aqueous hydrochloric acid (4×500 ml) and then saturated aqueous sodium bicarbonate solution (4×500ml). The organic phase was dried (MgSO4) and concentrated to give the title compound as a clear oil (10.8 g). 1H-NMR (CDCl3): δ=0.95(t,3H), 1.65(m,2H), 2.60(t,2H), 3.36(s,3H), 3.58(s,3H), 7.20(d,2H), 7.60(d, 2H) ppm.
