Reaction Steps

2-[1-(Ethoxyimino)propyl]-5-(3,4-ethylenedioxyphenyl)-3-hydroxycyclohex-2-en-1-one was prepared from 5-(3,4-ethylenedioxyphenyl)-3-hydroxy-2-propionylcyclohex-2-en-1-one and ethoxyamine hydrochloride following essentially the same procedure as that described in Example 1 part (iv). The product was obtained as an oil and was characterized by proton nuclear magnetic resonance spectroscopy. Pmr spectrum (CDCl3 ; δ in ppm): 1.08-1.40 (6H, 2xt); 2.27-3.25 (7H, m); 4.00-4.24 (6H, m); 6.65-7.27 (3H, m); 15.00 (1H, brs).
