Procedure:
A solution of borane dimethylsulfide complex (2M in THF, 14.4 mL) was added dropwise to a solution of 2-(2,3-difluoro-4-hydroxyphenyl)acetic acid (example 77, step a) (1.08 g) in tetrahydrofuran (25 mL) at 0° C. and the resulting mixture was allowed to warm to RT and stirred overnight. The reaction was quenched with methanol and when bubbling had ceased the solvent evaporated. The residue was purified by silica gel chromatography eluting with 4:1 isohexane:ethyl acetate to ethyl acetate gradient. The fractions containing product were combined and evaporated to give the subtitled compound as white solid. Yield 0.95 g.

Procedure:
3-Bromo-4-(methyloxy)benzonitrile (2.12 g, 10 mmol), THF (30 mL), and 1.5 M borane in THF (30 mL, 45 mmols) were combined and stirred under argon at reflux.

THF (30 mL), and 1.5 M borane in THF (30 mL, 45 mmols) was again added and the mixture refluxed for a total of ten days to drive the reaction to completion. The reaction was worked up by the cautious addition of ethanol followed by 1N HCl until the pH was 2. This mixture was then heated to 50° C. for 4 h. The solvents were pumped off, and the residue partitioned between EtOAc and water. The aqueous phase was washed 3× with EtOAc and adjusted to pH 10 by the addition of 2.5 N NaOH. The aqueous phase was extracted 3× with EtOAc. The combined organic phases were dried over anhydrous Na2SO4, filtered and concentrated to give the title compound.

The product fractions were collected and the solvent was evaporated to yield the title compound as a residue which contained about 10% of an impurity. (The product was used in subsequent steps without further purification.)

Procedure:
Triethylamine (0.031 mL, 0.23 mmol) was added to a solution of 1-(4-aminobutyl)-2-butyl-6,7-dimethyl-1H-imidazo[4,5-c]pyridin-4-amine (67 mg, 0.23 mmol) in dichloromethane (45 mL). The reaction mixture was cooled in an ice bath. Dimethylsulfamoyl chloride (0.025 mL, 0.23 mmol) was added. The reaction mixture was removed from the ice bath. The reaction mixture was allowed to stir at ambient temperature for ˜113 hours. Analysis by HPLC indicated that the reaction was not complete. The dichloromethane was removed under reduced pressure. 1,2-Dichloroethane (50 mL) was added and the reaction mixture was heated to 60° C. After 3 hours, more dimethylsulfamoyl chloride (2.5 μL) was added and heating was continued. After 22 hours the reaction temperature was raised to reflux and the reaction mixture was refluxed for 100 hours. The reaction mixture was extracted twice with water. The aqueous fractions were combined and concentrated under reduced pressure. The resulting residue was recrystallized from methyl acetate to provide 10 mg of N′-[4-(4-amino-2-butyl-6,7-dimethyl-1H-imidazo[4,5-c]pyridin-1-yl)butyl]-N,N-dimethylsulfamide as an off-white crystalline solid, m.p. 129.5-131° C.

Procedure:
A suspension of 24.8 g (0.1 mol) of 4-chlorophenyl 1-(1, 2, 4-triazol-1-yl)-cyclopropyl ketone with 19.8 g of 80% strength hydrazine hydrate in 40 ml of diethylene glycol was refluxed for 1 hour and cooled, and 14.3 g of powdered potassium hydroxide were added to the clear yellow solution. The mixture was refluxed, and the resultant water of reaction was then distilled off until the diethylene glycol again refluxed. After 1 hour, the mixture was poured into water and extracted with dichloromethane; after drying, the solvent was removed in vacuo and the residue remaining was distilled in a high vacuum. 13.5 g (57%) of the title compound were obtained as a yellowish oil, of boiling point 154°-156° C./0.05, which crystallized with melting point 67°-8° C.
