Procedure:
Benzyltriphenylphosphonium bromide (2.94 g) was dissolved in THF (23.0 mL), added at −20° C. with potassium tert-butoxide (1.07 g) in small portions, and stirred for 1 hour at the same temperature. Subsequently, a THF (6.0 mL) solution of methyl cis-4-formylcyclohexane carboxylate (1.00 g) was added dropwise over 35 minutes, and stirred for 1.6 hours at the same temperature. After raising the temperature to room temperature, it was stirred after adding water and extracted with toluene. The organic layer was washed with water and saturated brine in order. After drying over anhydrous sodium sulfate, the solvent was evaporated under reduced pressure.

Procedure:
To a vigorously stirred 1:1 mixture of methylene chloride/8% aqueous NaHCO3 (8 mL) at 0° C. is added triphosgene (28.4 mg, 0.096 mmol). After stirring the mixture at 0° C. for 5 minutes, (2R,4S)-4-amino-5-biphenyl-4-yl-2-methyl-pentanoic acid ethyl ester hydrochloride (100 mg, 0.287 mmol) is added and stirring is continued for 15 minutes. The organic phase is separated and dried over sodium sulfate. The solvent is removed under reduced pressure to furnish (2R,4S)-5-biphenyl-4-yl-4-isocyanate-2-methyl-pentanoic acid ethyl ester. Next, to a solution of 1H-pyrazole-3-carboxylic acid (32.2 mg, 0.287 mmol) in DMF (1 mL) is added diisopropylethylamine (0.05 mL, 0.287 mmol). After 15 min a solution of the above (2R,4S)-5-biphenyl-4-yl-4-isocyanato-2-methyl-pentanoic acid ethyl ester in DMF (1 mL) is added dropwise and the mixture is stirred at room temperature for 18 hours.

Procedure:
To a solution of 3a-(R)-benzyl-2-methyl-2,3a,4,5,6,7-hexahydro-pyrazolo[4,3-c]pyridin-3-one, L-tartrate (10.81 g, 0.0275 mol) in ethyl acetate (216.2 mL) at about −66° C. was added TEA (8.43 mL, 0.0605 mol). The mixture was stirred for about 1.5 hours. After removal of the precipitated salt by filtration, 3-benzyloxy-2-(2-tert-butoxycarbonylamino-2-methyl-propionylamino)-propionic acid (8.7 g, 0.0229 mol) and TEA (19.15 mL, 0.1374 mol) were added at about −35° C., followed by the dropwise addition of 50% PPAA in ethyl acetate (27.5 mL, 0.0458 mol). The mixture was stirred for about 2 hours at about −20° C. to about −27° C., then 1.5 hours while the temperature was slowly raised to about 0° C. The reaction mixture was poured into water and extracted with IPE, washed with 7% NaCl solution and concentrated in vacuo. The crude oil that was obtained was treated with IPE/hexane (50/50) to allow crystallization. The product was obtained as a white solid (10.3 g, yield 74.3%).

Procedure:
Sodium hydride (10 mg) (60% in oil) was added to a stirred solution of 2-butyl-7-methylimidazo[4,5-b]pyridine (48 mg) in dimethyl sulfoxide (5.0 ml) and the mixture was stirred for 30 minutes at ambient temperature. To this mixture was added a solution of 4-ethoxycarbonyl-1-(4-methanesulfonyloxymethylphenyl)-2-(1-trityl-1H-tetrazol-5-yl)pyrrole (193 mg) in dimethyl sulfoxide (2 ml). The mixture was stirred for 3 hours at ambient temperature and poured into brine. The mixture was extracted with ethyl acetate, dried over magnesium sulfate and evaporated in vacuo. The residue was purified by preparative thin layer chromatography to afford 2-butyl-3-[4-[4-ethoxycarbonyl-2-(1-trityl-1H-tetrazol-5-yl)-1-pyrrolyl]benzyl]-7-methyl-3H-imidazo[4,5-b]pyridine (123 mg) as a colorless viscous oil.
