Procedure:
HATU (0.31 g) was added to a solution of N-(3-chloro-2-fluorophenyl)-7-methoxy-6-(piperidin-4-yloxy)quinazolin-4-amine dihydrochloride (300 mg), diisopropylethylamine (0.45 ml) and 3-methyl-4-isoxazolecarboxylic acid (0.128 g) in methylene chloride (9 ml).

Procedure:
A mixture of CPS-0 (6.92 g contains 76% (5.26 g, 17.7 mmol) of oripavine), meta-chloroperoxybenzoic acid (MCPBA, 4.30 g) and glacial acetic acid (52 ml) is stirred at room temperature for 5 hours. The amount of oripavine is then expected to be not more than 1% by HPLC analysis. To the resulting 14-hydroxymorphinone mixture is added 5% Pd/C (0.55 g) and hydrogenation proceeds at room temperature at 48 psig of hydrogen for about 18 hours. The amount of unreacted 14-hydroxymorphinone is expected to be not more than 0.5% by HPLC analysis. The mixture is filtered to remove the catalyst and the filtrate is evaporated to almost dryness. The residue is dissolved in water and basified to pH 9 by ammonium hydroxide. The solids are collected by filtration and dried at 90° C. and under 25-inch Hg of vacuum for 3 hours to give crude oxymorphone (approximately 95% yield expected).

Procedure:
A 3.2 gram amount of NG -nitro-N2 -(tert-butyloxycarbonyl)-L-arginine was dissolved in a mixture of 40 ml of dry tetrahydrofuran and 1.4 ml of triethylamine. To the solution was added 1.4 ml of isobutyl chloroformate with stirring and cooling in an ice-salt bath. After additional stirring for 15 minutes, 0.87 gram of N-methyl-n-butylamine was added to the mixture. Then the reaction mixture was stirred continuously for 40 minutes at room temperature. The solvent was removed by distillation under reduced pressure, below 40° C. The residue was extracted with 100 ml of ethyl acetate and the extract was washed successively with a 10% aqueous citric acid solution, saturated sodium chloride solution, saturated aqueous sodium bicarbonate solution, and finally with saturated aqueous sodium chloride solution. The organic layer was dried over anhydrous Na2SO4, filtered and concentrated to give NG -nitro-N2 -(tert-butyloxy-carbonyl)-N-(n-butyl)-N-methyl-L-argininamide. This material was added to ethyl acetate containing 10% dry HCl and allowed to stand for 2 hours, and NG -nitro-N-(n-butyl)-N-methyl-L-argininamide hydrochloride was precipitated.

Procedure:
The product from Step A (11 g) was suspended in CH2Cl2 (75 mL), and TFA was added dropwise (75 mL). The resulting solution was stirred overnight at ambient temperature. The reaction solution was concentrated under reduced pressure, and the resulting residue was dissolved in CH2Cl2 (100 mL). Saturated aqueous NaHCO3 (100 mL) was added slowly with stirring. After 20 min the organic layer was separated, washed with water (10 mL) and then brine (30 mL), and dried over Na2SO4. The organic layer was then concentrated under reduced pressure and purified via silica gel chromatography (0-35% methanol/dichloromethane) to give the title compound (7.6 g).

Procedure:
Sodium triacetoxyborohydride (0.41 g, 2.0 mmol) was added to a solution of 5-(tert-butyl)-2-hydroxy-3-(6-(trifluoromethyl)pyridin-3-yl)benzaldehyde (0.35 g, 1.1 mmol) and 1-acetylpiperazine (0.24 mL, 1.8 mmol) in tetrahydrofuran (10 mL). The reaction mixture was stirred at room temperature under nitrogen for 16 hours. The reaction mixture was partitioned between ethyl acetate (25 mL) and saturated aqueous sodium bicarbonate solution (25 mL). The organic phase was dried with sodium sulfate, filtered and concentrated under reduced pressure to give a yellow syrup. The product was purified using flash chromatography on silica eluting with a solvent gradient of 0 to 100% ethyl acetate in hexanes to give a colorless oil which was dissolved in 1.25 M hydrochloric acid in ethanol (10 mL, 12.5 mmol). The mixture stood for 20 minutes and was then concentrated under reduced pressure to give a white solid which was triturated with diethyl ether (10 mL) and solid was filtered off to afford 1-(4-(5-(tert-butyl)-2-hydroxy-3-(6-(trifluoromethyl)pyridin-3-yl)benzyl)piperazin-1-yl)ethanone hydrochloride (0.32 g, 61% yield) as a white solid.
