Procedure:
7.4 g of 4-(naphthalene-1-yl)phenyl boronic acid prepared by a well known method and 7.0 g of conventional 1-bromopyrene were dissolved in 80 ml of dimethoxyethane (DME). Subsequently, 0.58 g of tetrakistriphenylphosphine palladium and 40 ml of 2M-sodium carbonate aqueous solution were added therein, followed by argon displacement. After heating and refluxing over 8 hours, it was stood to cool and then an organic layer was extracted therefrom by toluene. The organic layer was washed by saturated salt water, followed by drying through anhydrous sodium sulfate, and then the organic solvent was removed by an evaporator. The residue was refined through a silica gel chromatography (a developing solvent: toluene) and then 10.0 g of 1-(4-naphthalene-1-yl-phenyl)pyrene was obtained. (yield: 99%)

Then add isobutyl chloroformate (20.3 mL, 155.5 mmol) in a dropwise fashion. After the end of the addition, stir the mixture at 0° C. for 20 minutes. Then, add methyl (S)-4-(1-aminoethyl)benzoate (27.9 g, 155.5 mmol), and stir the mixture at room temperature for 1 hour. Add water (400 mL), separate the layers, and wash the organic layer with 1 M aqueous KHSO4 (500 mL), followed by saturated aqueous NaHCO3 (500 mL). Dry the organic phase over MgSO4, filter to remove the solids, and concentrate the filtrate under reduced pressure to furnish the title compound as a white solid (60 g, 97% yield). Mass spectrum (m/z): 339 ([M+H−Boc]+), 383 ([M+H−t-Bu]+), 439 ([M+H]+).

Procedure:
5-(Benzoxazol-2-yl)-2-(tetrahydropyran-4-yl)aminoaniline (see Working Example 20-2) (0.15 g, 0.484 mmol) was dissolved in DMF (3 mL) and water (0.1 mL), phenyl aldehyde (0.06 g, 0.561 mmol) was added followed by oxone (0.19 g, 0.310 mmol), and this was stirred at room temperature for 2.5 hours.

Procedure:
To a solution of 4.76 g (0.025 mol) of 1-methyl-5-phenyl-imidazol-2-thiol and 3.15 g (0.031 mol) of triethylamine in 250 mL of acetone was added 2.55 g (0.28 mol) of chloroacetone in 250 mL of acetone. The solution was stirred at room temperature for 16 hours. The acetone was removed by evaporation and the residue was partitioned between ethyl acetate and water. The ethyl acetate phase was washed with water, brine, and dried over magnesium sulfate. The solvent was evaporated from the dried solution to obtain as residue 6.16 grams of 1-methyl-5-phenyl-2[(2-oxopropyl)thio]imidazole which was purified by flash chromatography on silica gel using 2 percent methanol in chloroform as eluant.

Procedure:
To a solution of diethyl 2-methyl-4-(2-nitrophenyl)-6-hydroxymethyl-1,4-dihydropyridine-3,5-dicarboxylate (1.95 g) in pyridine (25 ml) was dropwise added a solution of benzoyl chloride (2.0 g) in methylene chloride (5 ml) over 5 minutes at 5° to 6° C. with stirring. The resultant mixture was stirred for 15 minutes at the same temperature and then at room temperature for 2 hours, and followed by stirring at 50° C. for an hour and a half. After the reaction was over, the pyridine was distilled off and to the residue was added ethyl acetate and water. The ethyl acetate layer was separated, washed with dil. hydrochloric acid twice and then aqueous solution of sodium bicarbonate, and dried over magnesium sulfate. The solvent was removed and the residue was soon crystallized by treating with diethyl ether and collected by filtration. These crude crystals were washed with a mixture of diethyl ether and a small amount of ethyl acetate to give crystals, which was recrystallized from ethyl acetate (25 ml) to give powders of diethyl 2-methyl-4-(2-nitrophenyl)-6-benzoyloxymethyl-1,4-dihydropyridine-3,5-dicarboxylate, m.p. 156° to 157° C.
