Procedure:
A 100 mL round-bottomed flask with stir bar is charged with 10 milliliters (mL) of liquid ammonia and 5.6 grams (g) (0.050 mol) of potassium t-butoxide. The resulting mixture is refluxed at -33° C. under a dry ice/acetone condenser and a nitrogen atmosphere. A solution of 2.4 g (0.010 mol) 1,2-dichloro-3,5-dinitrobenzene and 1.1 g (1.1 eq.) of 90% t-butyl hydroperoxide in 30 mL of N-methylpyrrolidinone is added dropwise over approximately 1 hour to the agitated refluxing liquid ammonia reaction mixture. Upon completion of the addition, the dry ice/acetone condenser is removed and the ammonia is allowed to evaporate under a stream of dry nitrogen. The crude 2,3-dichloro-4,6-dinitrophenol is isolated by pouring the reaction mixture into 50 mL of aqueous hydrochloric acid, extracted with ethyl acetate and the organic solvents evaporated under reduced pressure (15 mm). The yield of the product is 2.2 g (89%). This product is of sufficient purity to be used without further refinement.

Procedure:
In 30 ml of tetrahydrofuran was dissolved 800 mg of compound 6 followed by the addition of 1.2 g of 2-(tert-butoxycarbonyloxyimino)-2-phenylacetonitrile (BOC-ON) at room temperature and the mixture was stirred at that temperature for 2 hours. The solvent was then removed under reduced pressure and to the residue was added chloroform. The mixture was extracted with a 10% aqueous citric acid. The citric acid extract was adjusted to pH≥10 with 1N aqueous sodium hydroxide and extracted with chloroform. The extract was dried over anhydrous sodium sulfate and the solvent was removed under reduced pressure to give 900 mg of 7-tert-butoxycarbonylamino-5-benzyl-5-azaspiro[2.4]heptane (compound 10). 870 mg of this compound 10 was dissolved in 15 ml of ethanol and catalytic hydrogenation was carried out at 40° C. and 4.5 kg/cm2 in the presence of 500 mg of 10% palladium-on-carbon for 2 hours. The catalyst was then filtered off and the filtrate was concentrated under reduced pressure to give title compound 11. This product was used without purification in the substitution reaction.

Procedure:
(s)-1-Furfurylthio-3-((s)-4-methyl-2-phenoxyacetylaminovalerylamino)-2-heptanone (176 mg) obtained in Example 3 was dissolved in methanol (10 ml) and water (10 ml). To the solution was added sodium metaperiodate (82 mg), and the mixture was reacted at room temperature for 48 hours. Then, methanol was removed in vacuo, saturated brine was added to the residue, and the resultant mixture was extracted with chloroform. The extract was washed with saturated brine, dried over sodium sulfate, and filtered. The filtrate was concentrated and chromatographed on a silica gel column, eluting with hexane:ethyl acetate (1:1) to give the titled product (66 mg).
