Procedure:
Potassium tert-butoxide (67.5 mg, 1.1 mmol) was added to a stirred solution of N-(6,7-dichloro-2,3-dimethoxyquinoxalin-5-yl)ethanesulphonamide (Preparation 4) (200 mg, 0.55 mmol) in dry dimethylformamide (3 ml) under nitrogen at 20° C. After 5 minutes, methyl iodide (38 μl, 1.1 mmol) was added and the mixture was stirred at 20° C. for 2 hours. The mixture was concentrated under reduced pressure, partitioned between ethyl acetate and water, and the combined organic extracts were washed with dilute aqueous sodium hydroxide. The solution was dried (MgSO4) and concentrated under reduced pressure. The residue was purified by flash chromatography (eluting with dichloromethane) to give N-(6,7-dichloro-2,3-dimethoxyquinoxalin-5-yl)-N-(methyl)ethanesulphonamide (150 mg, 79%).

N,N-Dimethylformamide (0.25 ml, 3.2 mmole) was added in one portion and the reaction was allowed to warm to -40° C. Hydrochloric acid (1.0M, 20 ml) was added and the reaction was warmed to room temperature. The solution was washed with 20 ml of diethyl ether and the ethereal wash was discarded. The aqueous solution was made basic with aqueous sodium hydroxide and extracted with two 15 ml portions of chloroform.

Procedure:
Amine functionalized polymer of formula (Vc) is dissolved at 10 mg/mL in anhydrous DMF and divided into two portions. NHS-biotin (0.9 mg in 90 μL, 88 equivalents) (Pierce, 20217) and NHS-LC-LC-biotin (Pierce, 21343) at 10 mg/mL (1.5 mg in 150 μL, 88 equivalents) are dissolved in anhydrous DMF. The NHS-biotin and NHS-LC-LC-biotin solutions are immediately added to the two portions of polymer solution and allowed to mix on a shaker overnight in the dark. Excess reactant is removed by washing the solution using Amicon Ultra-4 mL 10 kD MWCO filter cartridges in a series of wash steps: First, the cartridge is first filled approximately halfway with water, and the reaction solution (by pipet) subsequently added directly into the water. Next, the cartridge is filled with water until it is full. The solution is mixed by pipetting up and down. Then, the cartridge is centrifuged at 2400 rpm for 30 minutes, or until the volume is reduced to 250 μL. The cartridge is then refilled with water 1 drop of 1M HCl is added; the solution is mixed, and centrifuged at 2400 rpm for 30 minutes, or until the volume was reduced to 2504. Next, the cartridge is refilled with water, 1 drop of 1M NaOH is added; the solution is mixed, and centrifuged at 2400 rpm for 30 minutes, or until the volume is reduced to 250 μL. The cartridge is then refilled with water, mixed and centrifuged at 2400 rpm for 30 minutes, or until the volume is reduced to 25 μL. This final step is repeated for a total of 5 washes.

Procedure:
A solution of (2S)-1-(2-methylbenzothiazol-5-yloxy)-3-piperazinylpropan-2-ol, a compound of formula (6) (75 mg, 0.14 mmol), and 3-(4-tert-butylphenyl)-5-chloromethyl-1,2,4-oxadiazole (40 mg, 0.16 mmol) in 10% trimethylamine/ethanol, was heated to 73° C. and allowed to stir overnight. The solvent was evaporated under reduced pressure, and the resulting residue chromatographed by PTLC (3% methanol/methylene chloride). The resulting oil was diluted with methylene chloride and placed on the high Vac. overnight, to yield (2S)-3-[4-({3-[4-(tert-butyl)phenyl](1,2,4-oxadiazol-5-yl)}methyl)piperazinyl]-1-(2-methylbenzothiazol-5-yloxy)propan-2-ol as a white solid (52 mg, 0.09 mmol).

Procedure:
DIBAL-H (11.0M in hexanes; 0.315 mL, 0.315 mmol) was added to a solution of 3-methyl-4-(5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridine-2-yl)benzonitrile (105.2 mg, 0.286 mmol) in CH2Cl2 (4.5 mL) at 25° C., and the resulting solution was stirred at 25° C. for 45 min. Additional DIBAL-H (1.0M in hexanes; 86 μL, 86 μmol) was then added, and the resulting solution was stirred at 25° C. for 30 min. Saturated aqueous Na/K tartrate solution (4.0 mL) was added, and the resulting mixture was vigorously stirred for 15 min, then partitioned between CH2Cl2 (40 mL) and saturated aqueous Na/K tartrate solution (10 mL). The organic layer was separated, and the aqueous layer was extracted with CH2Cl2. The combined organic extracts were dried over MgSO4, filtered, and concentrated in vacuo. Chromatographic purification of the residue (silica gel, 0-40% EtOAc/hexanes) provided 3-methyl-4-(5-(1-phenylcyclopropyl)thiazolo[5,4-b]pyridine-2-yl)benzaldehyde as a light-yellow foam.

Procedure:
To a solution of (±)-3-{[2-(4,5-diphenyloxazol-2-yl)-2-cyclohexen-1-yl]methyl}phenylamine (110 mg, 0.27 mmol) in methylene chloride (3 ml) was added benzenesulfonylisocyanate (0.037 ml, 0.27 mmol) at 5° C., and the mixture was stirred at room temperature for 1 hour. The reaction mixture was evaporated, and the residue was purified by silica gel column chromatography (methylene chloride-MeOH, 30:1 elution) to give (±)-1-benzenesulfonyl-3-{3-{[2-(4,5-diphenyloxazol-2-yl)-2-cyclohexen-1-yl]methyl}phenyl}urea (159.0 mg, 100%).

Procedure:
4-Methoxy-1,3-benzenedicarboxylic acid 3-monomethyl ester (formula 7) was prepared by adding at 20° C. under stirring 12 ml of concentrated sulphuric acid, d 1.84, to a suspension of 50 g of 4-methoxyisophthalic acid in 400 ml of methanol; stirring was then continued for 1 hour and then the mixture was poured into ice-water (400 ml). The precipitate was collected and stirred with a saturated solution of sodium hydrogen carbonate; the insoluble residue (15 g) was constituted by 4-methoxy-1,3-benzenedicarboxylic acid dimethyl ester. The filtered solution was adjusted to pH 4.8 by adding 6N hydrochloric acid, thus precipitating the desired monoester, which was collected and washed with water, yielding 28.1 g (52.5%) of white solid. By further acidification of the mother liquor unreacted 4-methoxy-1,3-benzenedicarboxylic acid (9 g) was precipitated and collected. In this way a total recovery of 44.2% was obtained by summing together the recovery of the acid and the dimethyl ester, thus allowing a useful yield of 96.7%.

Procedure:
A mixture of compound [11a] (0.55 g), acetic acid (2 ml), THF (2 mL) and water (2 mL) was stirred at 40-50° C. for 4 hours (TLC monitoring). The mixture was basified with 1 N aq. potassium hydroxide to pH 10-11 and the product was extracted with dichloromethane (3×20 mL). The combined organic layers were dried over sodium sulfate, filtered and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (elution with gradient ethyl acetate/hexane from 1:2 to 3:1 v/v) to give 0.18 g (43%) of the compound [11b] as a colorless oil. 1H NMR (CD3OD) is compatible with literature data.
