2. Preparation of (E)-2-[1-(3-chloro-2-propenyloxyimino)propyl]5-(1-methyl-1H-pyrazol-4-yl)cyclohexane-1,3-dione (Compound No. 1) STR15 To 200 ml of an ethanolic solution of 20.0 g (81 mmols) of 5-(1-methyl-1H-pyrazol-4-yl)-2-propionylcyclohexane-1,3-dione was added 210 ml (84 mmols) of 0.4 mol ethanolic solution of (E)-3-chloro-2-propenyloxyamine. The mixture was reacted for 8 hours with stirring. After completion of the reaction, the reaction mixture was concentrated under reduced pressure. The resulting crude product was purified by silica gel column chromatography (ethyl acetate) to give 12.5 g of the product. Physical properties: Melting point, 99° C. Yield, 46percent. 1 H NMR (CDCl3, TMS), ppm. delta1.13 (3H, t, J=7 Hz) 2.4-3.7 (7H, m) 3.83 (3H, s) 4.49 (2H, d, J=6 Hz) 5.9-6.5 (2H, m) 7.16 (1H, s) 7.29 (1H, s).
