Procedure:
Lithium hydroxide monohydrate (0.488 g, 20.40 mmol) was added to ethyl 4-[[1-[3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl]piperidin-4-yl]oxy]benzoate (2.22 g, 5.10 mmol) in MeOH (80 mL) and water (40.0 mL). The resulting suspension was stirred at 50° C. for 2 days. The reaction was cooled to room temperature, the methanol was evaporated and the aqueous residues treated with citric acid until precipitation ceased. The precipitate was collected by filtration, washed with water and dried to afford 4-[[1-[3-(trifluoromethyl)-[1,2,4]triazolo[4,3-b]pyridazin-6-yl]piperidin-4-yl]oxy]benzoic acid (2.020 g, 97%) as a solid.

Procedure:
2-n-Butyl-4-(5-methylsulfonyl-1,3,4-thiadiazol-2-yl)-semicarbazide (0.1 mole) dissolved in methanol (100 ml) is charged into a glass reaction vessel equipped with a mechanical stirrer and thermometer. Aqueous formaldehyde (0.2 mole; 37% concentration) is then added to the reaction vessel with stirring. Dilute aqueous potassium hydroxide is added to the reaction mixture to adjust the pH to between 7 to 8 and stirring is continued for a period of about 20 minutes resulting in the formation of a solid precipitate. The precipitate is recovered by filtration, is recrystallized and is dried under vacuum to yield the desired product 2-n-butyl-4-(5-methylsulfonyl-1,3,4-thiadiazol-2-yl)-1,2,4-triazolidin-3-one.

A mixture of the title D compound in Example 13, (3R*,4R*)-4-(3′-hydroxy-biphenyl-3-yl)-3-(naphthalen-2-ylmethoxy)-piperidine-1-carboxylic acid t-butyl ester (80 mg, 0.16 mmol), 2-chloroethyl methyl ether (57 μL, 0.62 mmol), K2CO3 (29 mg, 0.21 mmol), KI (16.6 mg, 0.1 mmol) and dimethylacetamide (1.5 mL) is stirred under argon for 16 h at 75° C. After the addition of a second portion of 2-chloroethyl methyl ether (35 mL, 0.38 mmol) and K2CO3 (44 mg, 0.32 mmol) stirring is continued for 18 h at 75° C. The mixture is filtered and the filtrate evaporated in vacuo. HCl (5M in 2-propanol, 1 mL, 5 mmol) is added to the crude residue and the mixture is stirred for 45 min. at RT. The reaction mixture is evaporated in vacuo and the residue purified using preparative HPLC (H2O/CH3CN). The combined pure fractions are treated with solid K2CO3 and CH3CN is removed in vacuo. The aqueous layer is extracted twice with CH2Cl2. The combined organic extracts are dried (Na2SO4) and evaporated in vacuo. The residue is stirred with HCl (5M in 2-propanol, 1 mL, 5 mmol) for 30 min. at RT. Evaporation of the solvent affords (3R*,4R*)-4-[3′-(2-methoxy-ethoxy)-biphenyl-3-yl]-3-(naphthalen-2-ylmethoxy)-piperidine hydrochloride as a brownish amorphous solid: MS (LC/MS) 468.4 [M+H]+; retention time 5.85 min (HPLC, Nucleosil C18; 5→100% CH3CN in H2O within 8 min).

The reaction mixture was poured into water, and the mixture was extracted with ethyl acetate. The organic layer was washed with saturated brine, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel chromatography (25% ethyl acetate/hexane to 70% ethyl acetate/hexane). To the residue were added ethanol (2 mL), tetrahydrofuran (2 mL) and 1N lithium hydroxide (0.45 mL), and the mixture was stirred at room temperature for 1 hr. The solvent was evaporated under reduced pressure, and water (10 mL) was added. The mixture was neutralized with 1N hydrochloric acid under ice-cooling, and stirred for 1 hr. The resulting precipitate was collected by filtration and dried to give the title compound (104 mg, 16%).
