Procedure:
N-(2-Aminoethyl)-(2-nitroimidazol-1-yl)acetamide (40 mg, 0.23 mmol) in methanol (0.5 cm3) was added to 2-oxo-1,4-dithiane (40 mg, 0.27 mmol) in acetone (0.2 cm3) under an atmosphere of dry nitrogen. The mixture was left at room temperature and monitored by n.m.r. spectroscopy until the reaction was complete. The bulk of the solvent was removed, and the resulting material purified by reverse phase h.p.l.c. using aqueous methanol as the eluant. The pure N-{2-[(2-mercaptoethylthio)acetylamino]ethyl}-(2-nitroimidazol-1-yl)acetamide (30 mg) was isolated as a pale yellow solid.

Procedure:
To a solution of 3-hexyl-6-methyl-6-[3-(1-triphenylmethyl-1H-imidazol-5-yl)phenyl]-3-azabicyclo[3.1.0]hexan-2-one (Preparation 74, 55 mg, 0.95 mmol) in methanol (1.5 ml) was added aqueous hydrochloric acid (2M, 0.5 ml) and the mixture was heated under reflux for 16 h. The reaction mixture was then cooled to room temperature and poured onto solid sodium hydrogen carbonate. Dichloromethane was added, the layers were separated and the organic extracts were dried (MgSO4) and concentrated in vacuo. The crude residue was chromatographed on silica gel eluting with ethyl acetate to give the title compound as a clear oil (21 mg, 66%).

Procedure:
A solution of 3,4-dichlorophenylacetic acid (23.59 g, 115 mmol) in thionyl chloride (66 mL, 905 mmol) was heated at 76° C. for 2.5 h and then evaporated under reduced pressure to yield 3,4-dichlorophenylacetyl chloride. A solution of 3,4-dichlorophenylacetyl chloride in cold, dry CH2Cl2 (90 mL) was added dropwise to an ice-cold solution of 13 (26.025 g, 104 mmol) and Et3N (16 mL, 115 mmol) in dry CH2 Cl2 (150 mL) with stirring under argon and ice-cooling over 30 min. The mixture was stirred at 25° C. for 21 h before the solvent was removed under reduced pressure. The residue was then dissolved in EtOAc and washed with 3N NaOH. The organic fraction was dried (MgSO4), filtered, and evaporated to yield 43.5 g (95%) of crude product.
