Procedure:
To a solution of 39.3 g of 4-cyanobenzaldehyde and 25.2 g of cyclopropyl methyl ketone in 60 ml of absolute ethanol was added 21 ml of 20% sodium hydroxide solution over a 25 minute period. The mixture was stirred for one hour at room temperature, cooled to 1° C. and 40 ml of cold water added. The solid material was collected by filtration and triturated with 450 ml of methylene dichloride and 150 ml of water at room temperature. The aqueous phase was extracted with methylene dichloride and the combined organic layers dried and concentrated in vacuo. The residue was recrystallized from absolute ethanol to give 45.0 g of 4-cyanophenylvinyl cyclopropyl ketone, m.p. 104° C.

Procedure:
To (4R)-4-(3-Amino-4-chlorophenyl)pyrrolidin-2-one (10 g, 47.62 mmol) was added a mixture of 12N HCl (30 mL) and ice cold water (20 mL) and cooled in ice. Sodium nitrite (3.7 g, 52.4 mmol) in 20 mL water was added dropwise. The mixture was stirred for 30 minutes. Potassium iodide (67.5 g, 404.8 mmol) in 100 mL of water was added dropwise at 0° C. The mixture was stirred for 1 h at 0° C. and then for 45 min at room temperature. One-hundred (100) mL of 20% IPA/DCM was added.

Procedure:
tert-Butyl-4-[3,4-dichloro-2-(chlorosulfonyl)phenoxy]piperidine-1-carboxylate (0.80 g, 1.8 mmol) was dissolved in 7N ammonia in methanol and stirred at room temperature for 20 min. The solution was concentrated in vacuo and then azeotroped once with toluene. The residue was redissolved in dichloromethane:trifluoroacetic acid/1:1 (20 ml) and stirred at room temperature for 15 minutes. The solution was concentrated in vacuo, then partitioned between ethyl acetate and saturated aqueous sodium hydrogen carbonate solution. The aqueous was reextacted with ethyl acetate (4 times), and the combined organics dried over anhydrous potassium carbonate. Concentration in vacuo afforded the title compound as a white powder (0.54 g).

Procedure:
A solution of Boc-D-Val-OH (940 mg), DMF (5 mL), and 2.0 M dimethylamine in THF (4.3 mL) was treated with HBTU (2.0 g) and stirred at ambient temperature overnight. The reaction mixture was added to saturated NaHCO3 (25 mL) and water (25 mL), then extracted 3×40 mL Et2O. The combined organics, along with the white insoluble material, were stripped of solvent and treated with TFA (10 mL) during 3 h, at which point the TFA was evaporated in vacuo. The residue was coevaporated with toluene, dissolved in THF (50 mL), treated with LiAlH4 (1.6 g), and the suspension held at reflux overnight. The reaction mixture was cooled in an ice bath and treated successively with IPA (10 mL) and 6M NaOH (5 mL); after stirring for 2h, the suspension was filtered, concentrated, and brine (50 mL) added. Extraction with DCM (3×15 mL), drying of the combined organics on MgSO4, and concentration gave a foμL-smelling yellow oil of (2R)-1-dimethylamino-2-amino-3-methyl-butane which was used without further purification.
