Procedure:
Sodium hydride (55 wt. %, 1.04 g) was added to a solution of 2-piperidinophenol (3.4 g) in N,N-dimethylformamide (35 ml) in an ice bath under a nitrogen atmosphere. The mixture was stirred at ambient temperature for 15 minutes. To the reaction mixture was added t-butyl N-(5-chloro-2-nitrophenyl)-N-methylcarbamate (5.25 g) in small portions. This mixture was stirred at 60° C. for 2 hours. At the end of this time the solvent was evaporated and water added to the residue.

The residue was purified by chromatography on a silica gel column using c-hexane/isopropyl ether=5/1 as the eluant to afford t-butyl N-[2-nitro-5-(2-piperidinophenoxy)phenyl]-N-methylcarbamate, of which Rf value was 0.27 in thin layer chromatography on a silica gel plate using c-hexane/isopropyl ether=5/1 as the eluant. A mixture of a solution of this product in toluene/methanol=7/3 (100 ml) and palladium on carbon (10%, 0.63 g) was vigorously stirred at room temperature under a hydrogen atmosphere for 14.5 hours. The catalyst was removed by filtration and the filtrate was concentrated. The residue was washed with cooled methanol and n-hexane to give the title compound (4.2 g).

Trethylamine(1.6 mL, 1.5 eq.) was added followed by an addition of methanesulfonylchloride (580 μL, 7.5 mmol) over 1 minute. After 1 minute at ˜0° C., the reaction was warmed to RT. After 1 hour the reaction was quenched with water, and partitioned between a saturated sodium bicarbonate solution and CH2Cl2. The aqueous layer was extracted with CH2Cl2 and the combined organic layers were washed with water (2 times), brine then dried over NaSO4, filtered and the solvent was removed in vacuo to give 455 mg of N-methanesulfonyl-2-aminobenzimidazole. HPLC shows the material to be 91% pure, (ret. time=3.70). LCMS: obs. M+H@212.1 amu. The material was carried on without purification.

Procedure:
A mixture of 2,5-dichloropyridine (10.0 g, 67.6 mmol) and piperazine (58.1 g, 675 mmol) was stirred at 165° C. for 2 h. The mixture was allowed to cool, slurried with dichloromethane (200 ml) and the solid collected by filtration. The filtrate was concentrated in vacuo and the procedure repeated. The residue after concentration of the filtrate was purified by flash chromatography twice (eluting with 1% ammonia, 10% methanol in dichloromethane) to give 1-(5-chloro-2-pyridyl)piperazine (12.25 g, 92%) as a tan solid. A portion of this solid (0.484 g, 2.45 mmol) was added to a solution of 3-dimethylaminomethyl-1H-pyrrolo[2,3-b]pyridine (0.392 g, 2.24 mmol) in toluene (10 ml) and the mixture heated at reflux under nitrogen for 6 h. The mixture was allowed to cool and the crystallised product filtered off. Recrystallisation from toluene gave the title compound (0.229 g, 31%), m.p. 196°-198° C.; (Found: C, 63.16; H, 5.60; N, 21.18.

Procedure:
2.6 ml of ethylchloroformate are rapidly added, dropwise, to a solution of 4.9 g of 1-carboxy-4-cyano-bicyclo[2.2.2]-octane and 3.8 ml of triethylamine in 130 ml of chloroform at -10° C. After 15 minutes of stirring, ammonia gas is introduced to the mixture for 10 minutes. The mixture is stirred for 10 minutes at 0° C., warmed to ambient temperature and after an hour, evaporated to dryness. The residue is stirred with water under heating, cooled, suction filtered, washed with water and dried. The 1-aminocarbonyl-4-cyano-bicyclo[2.2.2]octane [4.2 g (86% of theory); Rf value: 0.78 (Silica gel; methylene chloride/methanol/conc. aqueous ammonia=4:1:0.2)] obtained is suspended in 100 ml of acetonitrile/water (1:1), combined with 15.0 g of bis(trifluoroacetoxy) iodobenzene and stirred for 18 hours at ambient temperature. The reaction mixture is evaporated down to half its volume, shaken twice with ethyl acetate and the aqueous phase is adjusted to a pH of 12 to 13. The aqueous phase is extracted 3 times with ethyl acetate and the combined organic phases are washed with saturated saline solution and dried. The residue is dissolved in ethyl acetate acid and a little acetone and ethereal hydrochloric acid are added. The mixture is cooled in an ice-bath, suction filtered and the product is washed with ethyl acetate.
