Procedure:
To a solution of 5.0 g (0.0515 mol) of 3-fluoropyridine and 43.5 ml of 1-(phenylmethyl)piperazine in 300 ml of anhydrous diethylether was added dropwise, at boiling temperature, within 2.5 hours, 56 ml (0.112 mol) of a 2 molar solution of phenyllithium in a cyclohexane-diethylether mixture (7/3 v/v) and the resulting mixture was then kept at reflux temperature for a further 4 hours.

Procedure:
These solvents are readily prepared from commercially available materials by standard and well-known organic syntheses techniques. For example, to prepare 1,1-dichloro-2,2,3,3,3-pentafluoropropane, 2,2,3,3,3-pentafluoro-1-propanol and p-toluenesulfonate chloride are reacted together to form 2,2,3,3,3-pentafluoropropyl-p-toluenesulfonate. Then, N-methylpyrrolidone, lithium chloride, and the 2,2,3,3,3-pentafluoropropyl-p-toluenesulfonate are reacted together to form 1-chloro-2,2,3,3,3-pentafluoropropane. Chlorine and the 1-chloro-2,2,3,3,3-pentafluoropropane are then reacted together to form 1,1-dichloro-2,2,3,3,3-pentafluoropropane.

Procedure:
1-[3-({[tert-Butyl(dimethyl)silyl]oxy}methyl)phenyl]-4-(pyridin-2-yl)piperazine (240 mg) was mixed with THF (2 ml), and a 1 M hydrochloric acid (2 ml) was added thereto, followed by stirring at room temperature for 5 hours. A saturated aqueous sodium hydrogen carbonate solution and CHCl3 were added to the reaction mixture, and the organic layer was dried over MgSO4 and concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (hexane/EtOAc) to obtain {3-[4-(pyridin-2-yl)piperazin-1-yl]phenyl}methanol (166 mg).

Procedure:
To a round bottom flask was added 6-((2,4-difluorophenyl)ethynyl)-3-isopropyl-[1,2,4]triazolo[4,3-b]pyridazine (19.5 g, 65.4 mmol, Preparation #J.1) and concentrated H2SO4 (145 mL, 1630 mmol). The reaction mixture was heated to about 90° C. for about 15 min. The reaction mixture was diluted with ice water (1000 mL) and partitioned with DCM (500 mL). The aqueous layer was neutralized with 50% aqueous NaOH (about 350 mL) to about pH 7. The organic layer was isolated and the aqueous layer was extracted with DCM (3×500 mL). The combined organic extracts were dried over MgSO4, filtered, and concentrated in vacuo to give 19.5 g of crude material. The crude material was purified by silica gel chromatography using EtOAc/acetone (gradient, 1:0 to 0:1) to give title compound (17.1 g, 83%) as a brown solid. LC/MS (Table 1, Method a) Rt=2.41 min; MS m/z: 317.2 (M+H)+.

Procedure:
This acid was prepared according to the procedure of W. H. Meek et al. J. Chemical and Engineering Data, 14(3), 388, (1969). To a solution of 2,6-diisopropylphenol (Aldrich cat. # D12660-8) (37.0 ml, 0.20 mol) in anhydrous N,N-dimethylacetamide (150 ml) was added sodium methoxide (16.2 g, 0.30 mol). Carbon dioxide was passed through the mixture throughout the subsequent reaction period. The mixture was heated with stirring and the solvent was slowly distilled out during 2 hours of the period until the pot temperature reached to 180° C. The mixture was allowed to continue stirring at 180° C. for another 1.5 hours and then cooled to 90° C. The flow of carbon dioxide was discontinued and water (400 ml) was added. The mixture, after further cooled to room temperature, was washed with toluene (4×60 ml) and then treated with conc. hydrochloric acid in an ice-water bath to pH 3. The resulting mixture was extracted with diethyl ether (2×150 ml); the ether extract was washed with brine (100 ml) and dried over anhydrous magnesium sulfate. Removal of the solvent under reduced pressure gave 3,5-diisopropyl-4-hydroxybenzoic acid (10.4 g, 23%). Rf 0.5 (silica gel, 50% diethyl ether/hexane). MS (CI, CH4): m/z 223 M+1).
