Procedure:
A solution of 2-[(2-benzyl-2H-pyrazol-3-ylamino)-methylene]-malonic acid diethyl ester (7.0 g, 0.020 mol) in POCl3 (50 mL) was heated at reflux (130° C.) for 8 hours. The excess of POCl3 were distilled off and the reaction mixture cooled to 0° C., before careful addition of water (100 mL) and then aqueous NaOH (3N) until pH reached 7. The product was extracted with CH2Cl2 several times, and the combined orgnic phase were dried over Na2SO4 and concentrated under vacuo. Column chromatography (SiO2, EtOAc/Heptane 1/6) afforded 4.10 g (65%) of the title product as a white solid.

Procedure:
20.0 g (183.3 mmol) of 2-azabicyclo[2.2.1]hept-5-en-3-one, 8.8 g (274.7 mmol) of methanol, and 150 mL of toluene were put into a four-necked flask (300 mL volume) equipped with a hydrogen chloride introducing tube, a thermometer, and an exhaust tube. 6.7 g (183.8 mmol) of hydrogen chloride was introduced into the obtained mixture over a period of 2 hours through the hydrogen chloride introducing tube at room temperature.

Procedure:
Piperonaldehyde (45 g.), β-anilinopropionitrile (52 g.) and dimethylsulfoxide (96 ml.) were heated together to 120° C and a solution of sodium methylate (2.5 g.) in methanol (12 ml.) was added over a 5 min. period.

The crude product was purified by hplc using a Waters XBridge Prep C18 OBD column (5μ silica, 19 mm diameter, 100 mm length) eluted with decreasingly polar mixtures of water (containing 1% aqueous ammonia) and acetonitrile as eluents to give 6-[4-[(3-methylimidazol-4-yl)methyl]piperazin-1-yl]-3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazine.

Procedure:
Methanesulfonyl chloride (50 g, 436 mmol) was added to a solution of 2-bromo-1-(4-hydroxyphenyl)-ethan-1-one (85 g, 395 mmol) and triethylamine (48 g, 474 mmol) in tetrahydrofuran (1000 ml) at 0° C. and the mixture was stirred for 30 minutes at room temperature. The mixture was partitioned between water and ethyl acetate, and the organic layer was washed with brine, dried over magnesium sulfate. The solvent was evaporated under reduced pressure and the residue was washed with diisopropyl ether to afford 4-(2-bromoacetyl)phenyl methanesulfonate (96 g, 83%) as white crystals.

Procedure:
1.2 g (5 mmol) of ethyl (3-ethoxy-2-oxocyclohex-3-en-1-yl)(oxo)acetate were dissolved in 20 mL of ethanol and 25 mL (5.2 mmol) of hydrazine hydrate 98% were added dropwise. The solution was stirred at room temperature for 5 hours, then heated at 60° C. for further 5 hours. The solvent was removed in vacuo and the residue taken up with diethyl ether and the resulting precipitate collected by filtration giving 0.8 g of the title compound, that was employed in the next step without any further purification.

Procedure:
136.5 g (0.6 mole) of 2,4-dichloro-5-fluorobenzoyl chloride and 97 g (1 mole) of 1,1-dichloroethylene are successively added dropwise to a suspension of 84 g of anhydrous aluminum chloride in 300 ml of methylene chloride, while cooling with ice and stirring, during which the temperature should not exceed 30° C. The mixture is stirred at room temperature for 3 hours and poured onto a mixture of about 600 g of ice and 60 ml of concentrated hydrochloric acid, the organic phase is separated off and the aqueous phase is subsequently extracted three times with 100 ml of methylene chloride. The methylene chloride solution is washed with 100 ml of water and dried with sodium sulphate and the solvent is distilled off in vacuo. The residue (218.8 g) is heated at 130°-140° C. with 0.34 g of triphenylphosphine until the initially vigorous evolution of HCl has ended (about 3/4 hour). Distillation under a fine vacuum gives 167.1 g (96.4%) of 2,2-dichlorovinyl 2,4-dichloro-5-fluorophenyl ketone of boiling point 121°-123° C./0.13 mbar, melting point 64°-65° C.

Procedure:
A solution of ethyl-4-[3-(1-piperidinylmethyl)phenoxy]butanoate (6.1 g) and potassium hydroxide (6.0 g) in ethanol (50 ml) and water (50 ml) was heated under reflux during 0.5 h.
