Procedure:
To a stirred solution of (S)-4-[2-(4-amino-phenyl)-ethyl]-2,2-dimethyl-oxazolidine-3-carboxylic acid tert-butyl ester (150 mg, example 6b) in dry THF (0.2 ml) under an argon atmosphere was added sodium hydride (34 mg, 60% dispersion in mineral oil) and stirring was continued for 15 minutes. Trifluoro-methanesulfonic acid 1-(5-bromo-pyridin-2-yl)-2,2,2-trifluoro-ethyl ester (182 mg) was then added and the mixture was stirred overnight at room temperature. The reaction mixture was diluted with ethyl acetate and washed sequentially with water and with saturated brine.

Procedure:
Methanol (100 ml) was added to sodium acetate (1.97 g) and 5-chloro-2-cyanophenol (1.84 g, mp. 155°-157° C.) which was synthesized according to a known method.

Procedure:
To a dried 10 L jacketed reactor under a nitrogen atmosphere was charged 1-chloro-5-methyl-3-phenyl-hex-5-en-3-ol (167 g, 81.7 wt %, 610 mmol, 1.00 equiv), 1-bromo-4-((S)-1-isocyanato-ethyl)-benzene (219 g, 93.7 wt %, 911 mmol, 1.50 equiv), anhydrous tetrahydrofuran (3.00 L), and then 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU, 409 mL, 2.73 mol, 4.50 equiv). The resulting solution was agitated and refluxed (Tint=67-69° C., Text=75° C.) for 19 h, at which point HPLC analysis indicated ˜1A % (220 nm) of the 1-chloro-5-methyl-3-phenyl-hex-5-en-3-ol remained. The dark solution was cooled to Tint=20-25° C. Two liters of tetrahydrofuran were removed by distillation under reduced pressure. The remaining dark solution was diluted with 4.0 L of ethyl acetate and 1.0 L of hexanes. The resulting solution was washed with 4.0 L of a 1.0 M aqueous solution of hydrogen chloride (note: the wash is slightly exothermic). The aqueous solution was cut and the remaining organic solution was dried with anhydrous sodium sulfate, filtered and then concentrated to an oil via reduced pressure. The resulting material was subjected to flash silica chromatography (5-30% ethyl acetate/hexanes, 1.74 kg of silica) to produce 137.8 g of material (59 wt %, 3.1:1 diastereomeric ratio favoring the desired diastereomer

Procedure:
To a stirred solution of 3-hydroxymethylfuran (1.01 g., 10.3 mmol) and pyridine (0.87 g., 10.3 mmol) in 30 ml dry tetrahydrofuran at 0° under argon was added lauroyl chloride (2.36 g., 10.8 mmol).

Procedure:
4-(1-Propyl-piperidin-3-yl)-phenylamine (600 mg, 1.65 mmol) and 4-isopropylphenylsulfonyl chloride (397 mg, 1.81 mmol) were dissolved in tetrahydrofuran (25 ml). Triethylamine (760 μl, 5.44 mmol) was added and the reaction mixture stirred for 72 hours at room temperature. The solvent was evaporated under reduced pressure, the residue treated with diethyl ether (50 ml) and three times extracted with water (3×30 ml). The organic phase was treated with 1 molar HCl solution. The acidic aqueous solution was made alkaline with NaOH solution to pH 9-10 and then extracted with ethyl acetate (25 ml). The organic phase was dried over magnesium sulfate, filtered, and the solvent evaporated under reduced pressure to give the crude product (580 mg). The crude product was purified via silica gel chromatography with ethyl acetate. Fractions containing the product were combined, the solvent evaporated to yield the pure product which was then converted into the hydrochloride salt via adding a solution of 1 N HCl in diethyl ether. The precipitate was filtered off and dried in vacuo to give the pure product (283 mg, 39%).

Procedure:
5-[hydroxy-(tetrahydro-pyran-4-yl)-methyl]-3-methoxy-cyclopent-2-enone (1.1 g, 5 mmol) was dissolved in dichloromethane (25 ml) in a 50 ml round bottom flask fitted with a reflux condenser. Triethylamine (1.4 ml, 10 mmol) and then methane sulfonyl chloride (0.8 ml, 10 mmol) was added dropwise which caused the reaction to warm to reflux. After 10 minutes the reaction was quenched by the addition of 1 M hydrochloric acid (10 ml). The layers were separated and the organics collected, passed through a phase separation cartridge and the solvent removed in vacuo. The crude product was dissolved in methanol (25 ml) and anhydrous potassium carbonate (1.4 g, 10 mmol) added and the mixture was stirred at room temperature for 72 h. The solvent was then removed in vacuo and the residue dissolved in ethyl acetate (25 ml) and filtered to remove any solid. The filtrate was evaporated to dryness and the residue purified on by column chromatography (Hexane/EtOAc (7:3) to 100% EtOAc) to give 3-methoxy-5-[1-(tetrahydro-pyran-4-yl)-methylidene]-cyclopent-2-enone (938 mg).
