Procedure:
To a suspension of 4-(methylsulfonyl)aniline (10 mmol) in toluene (100 mL), trimethylaluminum (2M solution in toluene, 15 mmol) is added over 15 minutes. The reaction mixture is warmed to room temperature and stirred for 2.5 hours. A solution of benzonitrile (20 mmol) in toluene (50 mL) is added over 10 minutes and the reaction mixture is heated to 80°-85° C. After 20 hours, the reaction mixture is cooled to room temperature and poured over a slurry of silica gel in chloroform. After filtration, the residue is washed with a mixture of methylene chloride/methanol (2/1). The combined filtrates are concentrated in vacuo and the resulting yellowish solid is stirred with a mixture of hexane/ether (2/1, 1000 mL). The intermediate is filtered and washed with more of hexane/ether (2/1). The pale yellow solid N-[4-(methylsulfonyl)phenyl]benzenecarboximidamide is used in the next reaction without further purification.

Procedure:
To a stirred and hot solution of 7.35 parts of sodium cyanide in 50 parts of dimethyl sulfoxide is added dropwise a solution of 15.2 parts of α-bromo-2-chloro-m-tolyl 2-thienyl ketone in 25 parts of dimethyl sulfoxide at 60° C. Upon completion, stirring is continued for 2 hours at 60° C. The reaction mixture is poured onto water and the product is extracted three times with 240 parts of ether. The combined ether phases are washed three times with 100 parts of water, dried, filtered and evaporated. The residue is boiled four times in 80 parts of diisopropylether and the latter is each time decanted, yielding 2-[2-chloro-3-(2-thenoyl)phenyl]acetonitrile as a residue which solidifies on standing.

Procedure:
Phenol (72 mg, 0.77 mmol) and anhydrous potassium carbonate (106 mg, 0.77 mmol) were stirred in dry N,N-dimethylformamide (5 mL) under nitrogen for 1.0 hour. (±)(1R*,2S*,3S*,5S*)-3-(Acetoxymethyl)-5-(2-bromo-5,6-dichloro-1H-benzimidazol-1-yl)-1,2-cyclopentanediyl diacetate (400 mg, 0.770 mmol) was added and the mixture stirred at 80° C. (oil bath) for 18 hours. Volatiles were removed in vacuo and the residue partitioned between chloroform and water. The chloroform layer was dried (sodium sulfate) and volatiles evaporated. The residual oil was stirred in 4N ammonia in methanol (30 mL) at ambient temperature for 18 hours. Evaporation and chromatography of the residue on silica gel with elution by 2% methanol-chloroform gave (±)-(1R*,2S*,3S*,5S*)-5-(5,6-dichloro-2-phenoxy-1H-benzimidazol-1-yl)-3-(hydroxymethyl)-1,2-cyclopentanediol as white solid foam from ethyl acetate (215 mg, 68%); 1H-NMR(DMSO-d6) δ: 7.98 and 7.71 (both s, 2, aromatic CH), 7.6-7.3 (m, 5, C6H5), 5.07 (d, J=6.4 Hz, 1, OH), 5.0-4.75 (m overlapping t at 4.95, J=3.1 Hz, total 2, NCH and OH), 4.71 (d, J=3.9 Hz, 1, OH), 4.5-4.35 (m, 1, OCH), 3.9-3.8 (m, 1, OCH), 3.7-3.4 (m, 2, OCH2), 2.3-1.9 (m, 3, CH2 and CH); mass spectrum (CI): 409 (M+1).
