Procedure:
A solution of 3,4-dibromo-2,2-diphenylbutanenitrile 45 (7.5 g, 19.8 mmol) in THF (50 ml) was added dropwise to a suspension of tert-BuOK (11.1 g, 99 mmol) in THF (250 ml) at −78° C. After 1 h30, the brown mixture was poured into a mixture of ether and a saturated aqueous NH4Cl solution. After separation, the organic phase was washed twice with water and finally with brine. Drying over MgSO4 and evaporation gave an brown-orange oil which was chromatographied over silica gel (CH2Cl2/Hexane 25/75). The alkyne 46 was obtained as a slightly yellow oil (4 g, 93%).

Procedure:
A 20 mL DMF solution of N-bromosuccinimide (4.07 g, 22.9 mmol) was slowly added to a DMF solution (100 mL) of 2-phenyl-4-tert-butyl-phenol (4.93 g, 21.8 mmol), forming a dark green solution. After stirring in the dark for 48 h, the resultant dark red solution was poured into 500 mL of water, forming a cloudy solution. This was extracted with 95:5 hexane/toluene (3×200 mL), dried over MgSO4, filtered and the solvent removed to give 7 as a thick red oil. Yield: 6.32 g (95%).

Procedure:
3-[(1-Ethylpropyl)amino]-6-methyl-2,4-dinitrobenzyl alcohol (2.0 g; 0.007 mol) and 2,4-dichlorophenoxyacetyl chloride (used in excess over theory) are dissolved in benzene, and the solution stirred at 60° C. until tlc (silica gel-benzene) indicates the reaction to be complete. The reaction mixture is then cooled down, diluted with ether, and washed with dilute sodium bicarbonate solution until the washings became alkaline. The organic layer is then separated, dried over magnesium sulfate, and evaporated to afford a liquid residue, which solidifies gradually (3.3 g; 94%). Recrystallization of this solid from methanol affords 1.4 g of title product, melting point 103°-106° C.

Procedure:
2-[4-Isopropyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-propan-1-ol (329 mg, 1.0 mmol) is dissolved into anhydrous toluene (5 mL) and cooled in an ice bath to 0° C. with stirring under nitrogen. Tributyl phosphine (400 uL, 1.50 mmol) is added by syringe followed by 1-1′-azodicarbonyl-dipiperidine (405 mg, 1.50 mmol). Finally, 3-(4-Hydroxy-2-methyl-phenyl)-propionic acid methyl ester (200 mg, 1.20 mmol) is then added. The reaction is allowed to stir under nitrogen at 0° C. for 1 hour, then room temperature and monitored by TLC and HPLC. Upon completion, the reaction is diluted with hexanes and allowed to stir vigorously for 10 min. The resulting white precipitate is then filtered away and the solution is concentrated under vacuum. The residue is further purified using either EtOAc/Hexanes (1:9) or Acetone/Hexanes (1:9) gradients on silica gel chromatography to yield 3-(4-{2-[4-Isopropyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-yl]-propoxy}-2-methyl-phenyl)-propionic acid methyl ester (239 mg, 0.4725 mmol) or 45%.

Procedure:
2,3,4,6-Tetra-O-acetyl-1-thio-β-D-glucopyranose, obtained from the hydrolysis of 29 g. of S-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl) thiopseudourea hydrobromide as in "Methods in Carbohydrate Chemistry", Vol. II, page 436 (Whistler and Wolfrom editors, Academic Press Inc., 1963), was dissolved in 250 ml. of chloroform and cooled to 0°-5° C. in an ice bath. Anhydrous pyridine (20 ml.) was added, followed by 27.9 g. of trityl chloride. The mixture was stirred overnight at ambient temperature and the organic solution was extracted with dilute hydrochloric acid, washed with 5% aqueous sodium carbonate solution and with brine, dried over magnesium sulfate and evaporated under reduced pressure. The residue was crystallized from ether, then recrystallized from benzene-cyclohexane to give S-trityl-2,3,4,6-tetra-O-acetyl-1-thio-β-D-glucopyranose, m.p. 177.5°-179.5° C.

Procedure:
To a suspension of NaH (2.76 g, 69 mmol) in DMF (100 mL) was added dropwise a solution of (S)-tert-butyl 4-(3-hydroxy-2,2-dimethylpropyl)-2,2-dimethyloxazolidine-3-carboxylate (6.6 g, 23 mmol) in DMF (150 mL).
