Temperature: 125 °C

Procedure:
Into a three-neck 750 ml flask equipped with a mechanical agitator, thermometer and condenser were charged 250 g of 99.7% pure granular pentachlorobenzene and 440 g of 92% sulfuric acid which was heated to 104°-108° C. by means of an electric heating mantle. The flask was then charged with 100 g of 99% pure concentrated nitric acid. This concentrated nitric acid was gradually added over a period of 0.83 hours while the reaction mixture was stirred and the temperature of the mixture maintained at 104°-108° C. Following this addition, the reaction mixture was heated to 125° C. for one hour followed by further heating at 135° C. The reaction mixture was heated again to raise the reaction temperature to above 145° C. and to form a liquid melt of pentachloronitrobenzene. The reaction mixture was maintained at this temperature for about 30 minutes. Next, the reaction mixture was cooled to 30°-70° C. by switching off the heating mantle and blowing cool air on the flask for about 30 minutes. The reaction mixture was then filtered by suction. The pentachloronitrobenzene product in the filter cake was washed twice with about 500 ml of distilled water each time. After drying at room temperature for 24 hours, the product was analyzed by Vapor Phase Chromatography (VPC). In this specific example, the product was of exceptional quality with an assay of 99.74% pentachloronitrobenzene, less than 0.01% pentachlorobenzene and 0.26% hexachlorobenzene.

Then 1M KOtBu/tBuOH (576 μL, 0.0.576 mmol) in 9:1 i-PrOH/H2O (4 mL) was added and the mixture was subjected to five cycles of pressurizing with nitrogen to 40 psi followed by depressurization. The stirred mixture was then subjected to ten cycles of pressurizing with hydrogen to 435 psi followed by depressurization. The mixture was then stirred at 900 rpm under hydrogen (435 psi) at 40° C. for 18 hrs. The mixture was allowed to cool to room temperature and then carefully vented. The resulting precipitate was collected by filtration and washed with cold MeOH (100 mL) to afford (S)-(4-fluorophenyl)(4-((5-methyl-1H-pyrazol-3-yl)amino)quinazolin-2-yl)methanol as a white solid (13.8 g). Chiral HPLC indicated a >99% enantiomeric excess of the earlier eluting enantiomer.

The tube was flushed with Nitrogen and sealed with a Teflon septum and Nitrogen was bubbled in the solution for 10 minutes, allowing the gas to escape through a needle. After the removal of the needle, the reaction mixture was stirred at 110° C. for 15 hours. Then, the green suspension was allowed to reach room temperature, poured into ice-water and extracted with dichloromethane. The organic layer was collected, dried (MgSO4), filtered and concentrated in vacuum. The crude mixture was chromatographied over silica gel with CH2Cl2 100% and CH2Cl2/MeOH:95/5 to yield 3.56 g (97%) of 6-Todoquinoline as a light yellow solid.

The residue is dissolved in acetic acid (100 mL) and this solution slowly added to NH4Cl (34.2 g, 0.64 mol) dissolved in acetic acid (200 mL) at 50°-70°. The reaction is then heated to 90°-95° for two hours and 30 minutes, concentrated in vacuo, partitioned between water and the CH2Cl2, and the organic phase chromatographed over silica gel with CH2Cl2 -CH3CN (95:5) elution to give the product as an oil.

Procedure:
A solution of PdCl2(dppf)-CH2Cl2 adduct (0.582 g, 0.712 mmol), tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate (4.63 g, 14.96 mmol), 1-bromo-2-iodo-4-(trifluoromethyl)benzene (2.298 ml, 14.25 mmol), and potassium phosphate (9.07 g, 42.7 mmol) in 50 mL dioxane/25 mL water was heated to 80° C. for 2 hours. LC/MS showed mostly product, so the reaction mixture was poured into water and was extracted with DCM. The organics were dried over MgSO4 and concentrated. Purification of the crude residue by silica gel column chromatography (0-30% EtOAc/heptane) gave tert-butyl 4-(2-bromo-5-(trifluoromethyl)phenyl)-5,6-dihydropyridine-1(2H)-carboxylate (4.05 g, 9.97 mmol, 70.0% yield) as a clear oil. m/z (ESI) 430.2 (M+Na)+.

Procedure:
A mixture of 5.0 g of (±)-2-(1-naphthylmethyl)-6-phenylhexanoic acid and 2.27 g of (-)-norephedrine was dissolved in 50 ml of methanol, and the mixture was concentrated under reduced pressure. The residue was dissolved in 60 ml of ethyl acetate with heating to 40° C. and the solution was allowed to stand overnight at room temperature. The precipitate was collected by filtration and recrystallized three times from ethyl acetate to obtain 1.5 g of the norephedrine salt (melting point 128°-131° C.). The resulting salt was dissolved in 30 ml of methanol, and 5 ml of a 1N-hydrochloric acid was added to the solution. The mixture was extracted with diethyl ether, and the ethereal layer was washed with water, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to obtain 0.95 g of (+)-2-(1-naphtylmethyl)-6-phenylhexanoic acid as a colorless viscous oil.
