Procedure:
The mixture of N-(2,4-dimethoxybenzyl)-2,4,5-trifluoro-N-1,2,4-thiadiazol-5-ylbenzenesulfonamide (Preparation 647, 44 mg, 0.10 mmol), 2-pyridazin-4-yl-4-(trifluoromethyl)phenol (Preparation 712, 34 mg, 0.10 mmol), and potassium carbonate (55 mg, 0.40 mmol) in N,N-dimethylformamide (1.0 ml) was stirred at room temperature for 24 hours. The reaction mixture was poured into aqueous 2 M hydrochloric acid solution (5.0 ml) and filtered to give a solid. The solid was dissolved in dichloromethane (1.0 ml) and trifluoroacetic acid (1.0 ml) was added to the solution. The resulting solution was stirred for 16 hours. Methanol (5.0 ml) was added to the reaction mixture and filtered off polymeric solid. The filtrate was concentrated in vacuo to give a residue. The residue was passed through a 5 g SCX™ column with 1:1 dichloromethane:methanol solution and then 1:0.75:0.25 dichloromethane:methanol:7N ammonia solution in methanol. The filtrate was concentrated in vacuo and purified by HPLC. Yield 7.3 mg, 14%.

Procedure:
A mixture of 8.50 g (37.77 mmol) (4-bromophenyl) propiolic acid (S. Chimichi, et. al., J. Heterocyclic Chem. 20, 105 (1983)), 5.39 g (45.32 mmol, 1.2 equivs.) thionyl chloride and 50 mL benzene was stirred and heated at 75° C. for 3 hrs. The reaction was allowed to cool to room temperature and solvent was evaporated. The reaction vessel was charged with 50 mL of fresh benzene and the mixture cooled in an ice bath under an atmosphere of nitrogen. Added next, dropwise in 50 mL benzene, was 7.04 g (75.54 mmol, 2 equivs.) aniline. After addition was complete, the ice bath was removed and the mixture stirred at room temperature overnight. The mixture was poured into 150 mL water and the layers were separated. The aqueous layer was extracted with three 100 mL portions of ethyl acetate. The combined organic layers were then washed sequentially with 100 mL portions of 5% aqueous hydrochloric acid, water, 5 % aqueous sodium carbonate and water. The organic layer was dried, filtered and solvent was evaporated from the filtrate. The resulting solid was recrystallized from absolute ethanol to provide 3.93 g (13.09 mmol, 35%)3-(4-bromophenyl)-N-phenylpropiolamide as a white powder, mp=159°-160.5° C.

The mixture was further stirred for 30 mins. at room temperature and then for 40 mins. under reflux to prepare a solution of 3,4,5-trimethoxyphenyl isocyanate. After cooling, to the resultant solution was added 3-amino-4-(2-chlorophenyl)-6,8-dimethylquinoline (500 mg), and the whole was stirred at room temperature overnight. The reaction mixture was concentrated, and the residue was purified by a column chromatography on silica gel and recrystallized from dichloromethane to give 4-(2-chlorophenyl)-6,8-dimethyl-3-[3-(3,4,5-trimethoxyphenyl)ureido]-quinoline as colorless needles. Yield 490 mg (56.3%). m.p. 204°-206° C.

Procedure:
A dry 250 mL flask was charged with 2-tert-Butyl-5-methyl-2H-pyrazole-3-carbonyl chloride (1.00 g, 4.98 mmol) and THF (40 mL). 6-(3-Amino-benzoyl)-1,3-dihydro-indol-2-one (as prepared in Example 40, 1.0 g, 3.96 mmol) was added to the THF solution of the acid chloride, and the mixture was allowed to reflux for 3 h. The reaction mixture was then allowed to cool to room temperature. The room temperature reaction mixture was concentrated in vacuo. The solid residue was suspended in boiling EtOAc. The suspension was allowed to cool to room temperature before filtering to afford the 2-tert-Butyl-5-methyl-2H-pyrazole-3-carboxylic acid [3-(2-oxo-2,3-dihydro-1H-indole-6-carbonyl)-phenyl]-amide as a tan solid (0.984 g, 2.363 mmol, 60%).

Procedure:
483 g (3.5 moles) of potassium carbonate, 16 g (0.1 moles) of potassium iodide and 16 g (0.05 moles) of tetrabutylammonium bromide are added to a solution of 270 g (1 mole) of 1,8-dihydroxy-3-(hydroxymethyl)anthraquinone (aloe-emodin) in 3500 ml of DMF at 60° C.; the reaction mixture is heated at 80° C. for 1 h. It is cooled to 50° C. and 443 g (3.5 moles) of benzyl chloride are added dropwise in approximately one hour. At the end of the dripping, the reaction mixture is brought back to 80° C. and left at that temperature under stirring for 45-60 minutes. It is then cooled to 50° C. and 200 ml of methyl alcohol are added. It is cooled to 20-25° C. and the inorganic salts are removed by filtering. The organic solvent is distilled at 60-70° C. at reduced pressure and the residue is dissolved in 3200 ml of tetrahydrofuran at 60° C. Maintaining the temperature at 50-60° C., the organic phase is washed twice with 1200 ml of 2.5 molar aqueous sodium hydroxide and once with 1000 ml of a saturated solution of sodium chloride in water. The organic phase is concentrated at reduced pressure at 60° C. and the residue is recovered with 2700 ml of ethyl acetate. The suspension thus obtained is concentrated to approximately ⅓ of the initial volume by distillation of the solvent at reduced pressure. It is gradually cooled to 0-4° C. and kept at that temperature for 1 hour. The solid is filtered and washed with ethyl acetate (100 ml×2). The damp product is dried at 45° C. at reduced pressure for 12-14 hours, providing 334 g (yield 74%) of dibenzyl aloe-emodin having a purity of 98% (HPLC).

Procedure:
A mixture of 300 g dihydropyridine of Step 1 and 2 g freshly sublimed sulfur in 100 ml xylene was heated to 200°-210° C. for 30 minutes. When the development of hydrogen sulfide had subsided, the reaction mixture was cooled to room temperature, and ca. 100 g of Charcoal plus 1000 ml of ethyl acetate was added. This mixture was heated to reflux for 6 hours and then filtered through Celite filter aid. The filtrate was concentrated under vacuum and the residue was chromatographed on silica-gel, eluting with ethyl acetate/hexane to yield 78 g of the Step 2 title product.
