Procedure:
Bis (tetrahydroabietyl)2,4 di-tert-butyl phenyl phosphite was prepared by first reacting 206 g (1 mol) of 2,4 di-tert-butylphenyl phenol with 310 g (1 mol) of triphenyl phosphite catalyzed with 2 g of sodium methylate (or phenate) to obtain a nominal 2,4 di-tert-butylphenyl diphenyl phosphite. Phenol was distilled through a 20 cm Raschig ring packed column to 150° C. and 30 mm. The reaction terminates at 190° C. at 4 mm after distilling the calculated 1 mol of phenol. The product mixture contained approximately 85% of the desired 2,4,di-tert-butylphenyl diphenylphosphite. The remainder was identified as being predominantly a mixture of bis (2,4 -di-tert-butylphenyl) phenyl phosphite and unreacted triphenyl phosphite.

Procedure:
The preparation was carried out analogously to Example 56, using 0.200 g (0.506 mmol) N-(3-bromopyridin-2-yl)-N′-(2-methoxybenzyl)guanidine acetate, 0.106 g (0.759 mmol) (4-fluorophenyl)boric acid, 0.160 g (1.518 mmol) sodium carbonate, and 0.038 g (0.033 mmol) tetrakis-(triphenylphosphine)palladium(0). The mixture was likewise heated in a reaction block for 19 hr at 110° C. under a nitrogen atmosphere. Despite prolonging the reaction time to a total of 6 days and renewed addition of the starting materials sodium carbonate, (4-fluorophenyl)boric acid, and catalyst, the reaction reached an end point at which the starting material/product-ratio of 1:1 had not changed. After termination of the reaction, appropriate workup, and purification via preparative HPLC, 20 mg (0.048 mmol, 9.4%) pure N-[3-(4-fluorophenyl)pyridin-2-yl]-N′-(2-methoxybenzyl)guanidine was obtained in the form of the acetate salt (base/acetate in a ratio of 1:1).

The reaction mixture was diluted with ethyl acetate (15 mL), washed successively with 5% aqueous sodium hydrogen carbonate solution (5 mL) and saturated brine (5 mL), and dried over anhydrous sodium sulfate. Insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate/n-hexane=30/70→80/20), and the obtained solution was concentrated under reduced pressure. The residue was recrystallized from ethyl acetate to give the title compound (90 mg, 59%) as a white powder.

Procedure:
To a solution of 2-hydroxy-4-methoxy-benzonitrile (16.4 g, 134.1 mmol) in ethanol were added potassium carbonate (37.07 g, 268.2 mmol) and 2-iodopropane (40.16 mL, 402.3 mmol).

Procedure:
PyBOP (68.69 mg, 0.13 mmol), diisopropylethylamine (0.023 mL, 0.13 mmol) and (S)-2-Amino-1-[5-(4-trifluoromethoxy-phenyl)-1,3,4-oxadiazol-2-yl]-butan-1-ol (38.0 mg, 0.12 mmol) are added to a solution of (S)-4,4-Difluoro-2-[(morpholine-4-carbonyl)-amino]-heptanoic acid (34 mg, 0.12 mmol) in dry methylene chloride (4 mL) and the reaction mixture is stirred overnight at room temperature. The reaction is quenched with aqueous NaHCO3, extracted twice with methylene chloride, the organic extracts are dried over Na2SO4 and evaporated under reduced pressure.

Procedure:
The title compound was prepared in accordance with the general method of Example 190(F), from 2-bromo-6-(fluoromethyl)pyridine (109 mg, 0.57 mol) and 2-(but-3-ynyl)-4,6-difluoro-1-methyl-1H-benzo[d]imidazole (126 mg, 0.57 mmol). The crude residue was purified over silicagel chromatography (prepacked 25 g silicagel column, DCM/MeOH: from 100/0 to 99/1 as eluent) to afford 43 mg of a light brown solid. The resulting solid was dissolved in Dioxane and 0.5N HCl in dioxan was added (0.14 mL, 0.07 mmol). A green solid was formed and it was collected by filtration and washed with AcOEt. The chlorhydrate salt was dissolved in MeOH, neutralized by saturated NaHCO3. The aqueous layer was extracted twice with AcOEt. The organic layer was dried over MgSO4 and the solvent removed under reduced pressure to afford 9 mg of 4,6-difluoro-2-(4-(6-(fluoromethyl)pyridin-2-yl)but-3-ynyl)-1-methyl-1H-benzo[d]imidazole (Yield: 5%) as purple oily solid (Mp=103° C.-104° C.).

Procedure:
To a stirred solution of 0.10 g of 10,11-dihydro-10-(4-amino-3-methoxybenzoyl)-5H-pyrrolo[2,1-c][1,4]benzodiazepine in 2 ml of methylene chloride is added 60 mg of triethylamine followed by a solution of 56 mg of n-butylsulfonyl chloride in 0.5 ml of methylene chloride. After stirring at room temperature for 2 hours, the reaction mixture is evaporated in vacuo to a residue which is dissolved in methyl alcohol, stirred for 1 hour and evaporated in vacuo to a residue which is treated with 2 ml of NH4Cl and extracted with 15 ml of ethyl acetate. The organic extract is washed with saturated NaHCO3, brine, dried (Na2SO4), filtered through hydrous magnesium silicate and the filtrate evaporated to a residue. The residue is stirred with ether-hexanes to give 0.14 g of light yellow solid. MS(CI):454(M+H).
