Procedure:
Ethyl 3-(3-aminoquinolin-4-ylamino)-2,2-dimethylpropanoate (see Example 26 Parts A through D, 9.0 g, 31.3 mmol) was treated according to a modification of the method described in Part B of Example 8 using trimethyl orthovalerate in lieu of trimethyl orthobutyrate. Prior to the addition of trimethyl orthovalerate (6.1 mL, 35 mmol) and pyridinium p-toluenesulfonate (0.050 g), the reaction was heated at reflux for 15 minutes and then cooled slightly. The reaction was heated at reflux for five hours, allowed to cool to ambient temperature, stirred overnight, and concentrated under reduced pressure to provide 11.2 g of ethyl 3-(2-butyl-1H-imidazo[4,5-c]quinolin-1-yl)-2,2-dimethylpropanoate.

Procedure:
An optically-active compound of 4-(3-methyl-1,6-diazaspiro[3.5]non-6-yl)-7H-pyrrolo[2,3-d]pyrimidine (25 mg) was mixed with 1-cyanoacetyl-3,5-dimethylpyrazole (32 mg) and 1,4-dioxane (750 μl), and the mixture was stirred at 100° C. for 3.5 hours. The mixture was cooled to room temperature. Thereto were added water and saturated aqueous sodium bicarbonate solution, and the mixture was extracted with ethyl acetate. The separated aqueous layer was extracted with ethyl acetate five times, and the combined organic layer was washed with water and concentrated under reduced pressure. The resulting residue was purified by silica-gel thin layer chromatography (eluent: chloroform/methanol=9/1). The resulting residue was purified by silica-gel thin layer chromatography (eluent: ethyl acetate/methanol=93/7) again. The resulting solid (8.0 mg) was slurry-washed with n-hexane/ethyl acetate solution to give the titled compound (6.7 mg).

Procedure:
30 g of [1-(4,5,6,7-tetrahydro-4,4,7,7-tetramethylbenzo[b]thien-2-yl)ethyl]triphenylphosphonium bromide and 9.5 g of 4-ethoxycarbonylbenzaldehyde are suspended in 300 ml of butylene oxide and the mixture is heated at reflux for 4 hours. The thus-obtained solution is concentrated to one third of the original volume in a water-jet vacuum, poured into 500 ml of a methanol/water mixture (6:4) and extracted several times with hexane. The organic phase is washed three times with water, dried over sodium sulphate and evaporated. There is obtained a light brownish oil which is purified by filtration over silica gel (eluting agent hexane/ether 19:1). After recrystallization from hexane, there are obtained 11.3 g of ethyl p-[2-(4,5,6,7-tetrahydro-4,4,7,7-tetramethylbenzo[b]thien-2-yl)propenyl]benzoate in the form of colorless crystals, m.p. 118°-120° C.

Procedure:
11.0 g (0.206 mol) of sodium methoxide is suspended in 130 ml of methanol. Then isoamyl nitrite (27 ml, 0.206 mol) and 25 g (0.129 mol) of 1-(4-Methylsulfanyl-phenyl)-butan-1-one dissolved in 70 ml of tetrahydrofuran (THF) are added and the reaction solution is stirred at room temperature for 1.5 days. After concentrating, water and acetic acid are added to neutralise. The crude product is extracted with ethyl acetate, washed with brine, dried over MgSO4, and concentrated. The residue is purified by column chromatography on silica gel with ethyl acetate-hexane (15:85) as an eluent. The structure is confirmed by the 1H-NMR spectrum (CDCl3). δ[ppm]: 1.14 (t, 3H), 2.52 (s, 3H), 2.72 (q, 2H), 7.25 (d, 2H), 7.89 (d, 2H), 8.01 (s, 1H).

Procedure:
The wet cake was charged to a flask. Water (8×1 g per g of oripavine) was charged. Agitation was turned on and nitrogen sweep was initiated. c-HCl (0.3 mL per g of oripavine) was added to form a solution (pH=about 4 to 5). A charcoal treatment and filtration was conducted when the color was dark. c-NH4OH (˜1 mL per g of oripavine) was added to adjust pH=about 9 to 10 to form a precipitate. The mixture was stirred at room temperature for 1 hour, then was filtered and washed with water (5×1 mL per g of oripavine). The resulting solid was dried under flowing air at room temperature or 1 hour to give a solid. The solid was further dried under house vacuum at 75° C. for 16 hours to give the product as a tan solid. The weight of solid should range from 0.8 g to 1.0 g per g of oripavine with peak area >95%, wt/wt 90 to 95% and water content 3 to 5%.

Procedure:
To 5,6-difluoro-2,2-dimethyl-3H-benzofuran-7-carboxylic acid (735) (0.75 g, 3.29 mmol) was added 1.0 M of borane tetrahydrofuran complex solution (12 mL), and the mixture was stirred at room temperature overnight. The reaction was cooled to 0° C., acidified with 5 N HCl to pH 1, and then neutralized to pH 8 with 5 N NaOH. The mixture was extracted with EtOAc (80 mL×3) and the combined organic phase was washed with water (50 mL), dried over anhydrous sodium sulfate, and the solvent removed in vacuo. The product was purified by prep HPLC to yield (5,6-difluoro-2,2-dimethyl-3H-benzofuran-7-yl)methanol (736) (0.4 g, 57%). 1H NMR (400 MHz, DMSO-d6) δ 7.18 (t, J=9.0 Hz, 1H), 4.38 (s, 2H), 2.97 (s, 2H), 1.40 (s, 6H).

Procedure:
HATU (350 mg, 0.92 mmol) was added to CH3CN (5 mL) at 0° C. After stirring for 5 min, the mixture was added to a solution of 4-(5-(3,5-dichloro-4-fluorophenyl)-5-(trifluoromethyl)-4,5-dihydroisoxazol-3-yl)-2-methylbenzoic acid (200 mg, 0.46 mmol), 5-(aminomethyl)-3,3-dimethylbenzo[c][1,2]oxaborol-1(3H)-ol hydrochloride (157 mg, 0.69 mmol), and TEA (186 mg, 1.83 mmol) in CH3CN (8 mL). Then the solution was stirred at rt for 2 h. The solution was acidified with HCl (1 N) and extracted with EA. The combined organic layers were washed with brine, dried over Na2SO4, and concentrated under reduced pressure. The residue was purified by prep-TLC (PE:EA=2:1) to give the final title compound (150 mg, yield 54%). 1H NMR (300 MHz, DMSO-d6): δ 8.98 (s, 1H), 8.92 (t, J=6.0 Hz, 1H), 7.78 (d, 2H), 7.62-7.58 (m, 3H), 7.48-7.45 (m, 1H), 7.33-7.27 (m, 2H), 4.49 (d, 2H), 4.39-4.25 (m, 2H), 2.36 (s, 3H), 1.42 (s, 6H); HPLC purity: 97.6% at 254 nm; MS: m/z=609 [M+H]+.
