Procedure:
Starting with 2-chloro-4-methylpyridine II, treatment with n-butyllithium in the presence of N,N-dimethylaminoethanol in hexane, followed by addition of carbon tetrabromide in THF affords 2-bromo-6-chloro-4-methylpyridine III. Compound III undergoes a palladium coupling with boronic acid IV in the presence of a base, such as Na2CO3, in a suitable solvent, such as DME, to give chloropyridine V.

Procedure:
0.28 g of potassium carbonate and 0.77 g of N,N'-dicyclohexylcarbodiimide were added to a solution mixture comprising 1.0 g of 2-chloro-4-methanesulfonyl-3-methoxycarbonyl benzoic acid, 0.38 g of 1,3-cyclohexane dione and 30 ml of t-amyl alcohol. The mixture was stirred at 80° C. for 3 hours. It was concentrated under reduced pressure, and an aqueous potassium carbonate solution was added thereto. Insoluble substances were removed by filtration. The filtrate was washed with chloroform, then acidified by an addition of concentrated hydrochloric acid and extracted with chloroform. The chloroform layer was washed with water and with a saturated sodium chloride aqueous solution and dried over anhydrous sodium sulfate. Then, the solvent was distilled off under reduced pressure to obtain a crude desired product. This crude product was crystallized from ethanol to obtain 0.3 g of the desired product. Melting point: 160-162° C.

Procedure:
To a mixture of (R)-2-methyl-CBS-oxazaborolidine (1.0 M in toluene, 1.5 mL, 1.5 mmol, 0.1 equiv.) in tetrahydrofuran (10 mL) under a nitrogen atmosphere at −25° C. was added a solution of borane (1.0 M in tetrahydrofuran, 9.0 mL, 9.0 mmol, 0.6 equiv.). A solution of 3-chloro-1-(3-chloro-5-fluorophenyl)propan-1-one (3.32 g, 15.0 mmol) in tetrahydrofuran (10 mL) was added dropwise over a period of 25 min, and the reaction mixture was stirred for an additional 30 min at −25° C. Methanol (10 mL) was added slowly to quench the reaction, followed by the slow addition of hydrogen chloride solution (1.0 M in diethyl ether, 20 mL) at −25° C. All volatiles were removed under reduced pressure. Hexane (100 mL) was added, and the white salt of the chiral auxiliary was filtered through a pad of celite and washed with hexane (2×25 mL). The filtrate was concentrated under reduced pressure to give (1S)-3-chloro-1-(3-chloro-5-fluorophenyl)propan-1-ol as viscous, colorless oil (Yield: 3.34 g (100%). Chiral purity: 93.4%, [□]D25=−10.3° (c=10 mg/mL, CHCl3)). This material was dissolved in 70 mL of methanol/acetonitrile. 500 □L of the resulting solution was repetitively injected onto the Supercritical Fluid Chromatography instrument, and the baseline resolved enantiomers were separately collected using the conditions described below. The chiral purity of each enantiomer was determined under the same Supercritical Fluid Chromatography conditions using a Chiralpak AD-H 5□m, 250 mm×4.6 mm ID column at 2.0 mL/min flow rate using Analytical Supercritical Fluid Chromatography (Berger Instruments, Inc. Newark, Del.). The chiral purity of the product was found to be 99.8%.

To a solution of 3.0 g of sodium hydride (50% dispersion in oil) in 300 ml of anhydrous tetrahydrofuran under argon was added 14.0 g of N-[3-(6-chloro-3-pyridazinyl)phenyl]acetamide. The solution was stirred for 0.5 hours, then 3.9 ml of methyl iodide was added. After stirring for 2 hours, the solution was poured onto 400 ml of water and extracted with 100 ml portions of dichloromethane. The combined extracts were dried, concentrated in vacuo and chromatographed on hydrated magnesium silicate with dichloromethane-methanol (98:2) as eluant. The fractions containing the desired product were combined, concentrated in vacuo and recrystalized from acetone-hexane to give 14.1 g of cream crystals, mp 109°-112° C.

Procedure:
To a solution of methyl 6-chloro-5-hydroxynicotinate (3.71 g) in DMF (30 mL) were added potassium carbonate (5.47 g) and benzyl bromide (2.59 mL), and the mixture was stirred at room temperature for 30 min. Water was added to the reaction mixture at 0° C., and the resulting precipitate was collected by filtration. The obtained crude crystals were washed with water and hexane, and dried at 50° C. for 15 min under reduced pressure to give a crude product of the title compound (4.57 g) as a pale-yellow solid.

Procedure:
3.33 g (10 mmol) of 9-bromo-10-phenylanthracene was dissolved into 80 mL of tetrahydrofuran (abbr.: THF) and cooled to −78° C., and then 7.5 mL (12.0 mmol) of n-BuLi (1.6 mol/L) was dropped into the reaction solution using a dropping funnel and stirred for 1 hour. A solution in which 5 g (20.0 mmol) of iodine was dissolved in 20 mL of THF was dropped and further stirred for 2 hours at −78° C. After the reaction, an aqueous sodium thiosulfate solution was added to stop the reaction. An organic layer was washed with an aqueous sodium thiosulfate solution and a saturated sodium chloride solution and dried with magnesium sulfate. After natural filtration, the filtrate was concentrated, and the obtained solid was recrystallized with ethanol, thereby obtaining 3.1 g of objective 9-iodo-10-phenylanthracene as a light-yellow solid with a yield of 83%.
