Procedure

Ethoxyamine hydrochloride (0.3 g) and then aqueous sodium hydroxide (0.12 g in 1 ml of water) were added to a solution of 2-butyryl-3-hydroxy-5-(2-methyl-5-thiazolyl)cyclohex-2-en-1-one (0.7 g) in ethanol (50 ml) at 20° C. with stirring. After 20 hours, the mixture was diluted with water (200 ml) and then extracted with chloroform (2×100 ml). The dried (MgSO4) organic extract was evaporated to give 2-[1-ethoxyimino)butyl]-3-hydroxy-5-(2-methyl-5-thiazolyl)cyclohex-2-en-1-one (0.75 g, 95%) as a nearly colourless oil which was characterised by proton magnetic resonance spectroscopy (CDCl3 ; δ in ppm); 0.96 (3H, t); 1.31 (3H, t); 1.7 (2H, m); 2.65 (3H, s); 2.5-3.8 (7H, m); 4.10 (2H, q); 7.37 (1H, s); 15.1 (1H, brs).
