Procedure:
P2O5 (5.00 g, 35 mmol) was treated with H2SO4 (4.5 mL, 81 mmol) at 0° C. in a 100 mL round bottom flask. Diethyl 2-(2-(2,3-dichlorophenyl)-2-methylpropanoyl)malonate (0.500 g, 1.0 mmol) was added, and the mixture was stirred at 25° C. for 1.5 hours. The reaction was quenched with ice, extracted with EtOAc (2×50 mL), and the combined organic layers were washed with brine (50 mL).

Procedure:
1.58 g(5 m mol) of DL-α-hydroxy-4-(p-methoxybenzyloxycarbonyl)phenylacetic acid were suspended in 10 ml of anhydrous methylene chloride and ice-cooled. To this suspension were added dropwise 5 ml of anhydrous methylene chloride solution containing 0.68 g(6 m mol) of chloroacetyl chloride with stirring over the course of 5 minutes. Then the temperature of the solution was raised slowly to ambient temperature, and the solution was stirred for 30 minutes to give a clear solution, The reaction mixture was poured into 20 ml of ice-water and adjusted to pH 2.5 with an aqueous sodium hydrogen carbonate solution. The organic layer was separated and the aqueous layer was extracted several times with methylene chloride. The combined organic layers were washed with water and dried over anhydrous magnesium sulfate. The solvent was removed in vacuo to give a pale yellow oily residue, which then was dissolved in 20 ml of benzene and left overnight in an ice-box, yielding 1.52 g (78%) of crystalline DL-α-chloroacetoxy-4-(p-methoxybenzyloxycarbonyl)phenylacetic acid of mp. 121°~125° C.

Procedure:
In a mixture of water (0.5 mL) and ethyl acetate (1 mL)was dissolved 2-(chloromethyl)pyridine hydrochloride (246 mg, 1.5 mmol). This solution was neutralized with the addition of sodium hydrogencarbonate. The organic layer was separated, and the remaining aqueous layer was subjected to extraction twice with ethyl acetate. The organic layers were combined and dried over magnesium sulfate, followed by concentration under reduced pressure to give 2-(chloromethyl)pyridine. To a suspension of (3aR*,10aS*)-4-(phthalimidoacetyl)-2,3,3a,4,9,10a-hexahydrobenzo[b]cyclopenta[e][1,4]diazepin-10(1H)-one (389 mg, 1.0 mmol) in N,N-dimethylformamide (3 mL), which was cooled to 0° C., was added sodium hydride (60% liquid paraffin dispersion, 44 mg, 1.1 mmol). The mixture was stirred for 3 minutes at the same temperature and for 10 minutes at room temperature. To this mixture was added a solution of the 2-(chloromethyl)pyridine, which was produce by the above-mentioned procedure, in N,N-dimethylformamide (0.5 mL). The mixture was stirred for 3 hours at room temperature. To the reaction mixture was added water, and resulting precipitate was collected by filtration, which was recrystallized from chloroform-ethanol-diisopropylether to give 232 mg (yield 48%) of the titled compound, m.p. 227°-229° C.

Procedure:
4-Bromomethyl-2,6-di-tert-butyl-phenol (2.42 g, 0.008 mole) was dissolved in 50 mL of dry tetrahydrofuran. In a separate conical flask benzene-1,4-diamine (p-PDA) (1.728 g, 0.016 mole) was dissolved in 25 mL of tetrahydrofuran and solution was transferred to a cylindrical funnel with pressure equalizing tube. Three-necked round-bottom flask containing solution of 4-Bromomethyl-2,6-di-tert-butyl-phenol was kept in oil-bath at 85° C. Solution in the flask was continuously stirred with the help of magnetic stirrer. Benzene-1,4-diamine solution was added drop-by-drop, from funnel to the flask in acidic medium for a span of 4-5 hours till all the solution was poured out. The reaction was terminated after that and the final reaction mixture was allowed to attain room temperature. The product was purified using silica gel column chromatography. Product was identified by 1H-NMR. The yield of 4-[(4-Amino-phenylamino)-methyl]-2,6-di-tert-butyl-phenol was 2.24 g (85%).

A solution of the compound (3.86 g, 7.32 mmol) obtained in Example 81-1), 1-methyl-1H-pyrazole-4-boronic acid pinacol ester (1.68 g, 8.06 mmol), tetrakis(triphenylphosphine)palladium(0) (850 mg, 0.73 mmol), and potassium carbonate (2.02 g, 14.65 mmol) in 1,2-dimethoxyethane (50 mL) and water (25 mL) was heated to reflux overnight with stirring. The reaction mixture was cooled to room temperature, water (20 mL) was added to the reaction mixture, the mixture was extracted with ethyl acetate, and the organic layer was washed with saturated sodium chloride solution and dried with anhydrous sodium sulfate. After concentration under reduced pressure, the residue was purified by silica gel chromatography (ethyl acetate:methanol=100:0 to 70:30) to obtain the title compound (3.87 g, quant.) as a yellow solid.

Procedure:
To a round bottom flask, 2-[1-(2,2-dimethylpropyl)-3-methyl-2-oxo-2,3-dihydro-1H-imidazo[4,5-b]pyridin-5-yl]-4-formylbenzonitrile (30-1) (70 mg, 0.2 mmol) was added under nitrogen, dissolved in THF (1 mL), and cooled to −78° C. 3M methylmagnesium bromide (0.08 ml, 0.24 mmol) was added slowly to the cooled solution and allowed to stir for 30 minutes. The reaction was warmed to room temperature for 30 minutes until complete conversion over starting material. The mixture was diluted with methanol, and passed through a syringe filter. The solution was purified using reverse phase chromatography (10-100%, 0.1% TFA in H2O/Acetonitrile) and the desired fractions were collected and concentrated to produce 2-[1-(2,2-dimethylpropyl)-3-methyl-2-oxo-2,3-dihydro-1H-imidazo[4,5-b]pyridin-5-yl]-4-[(1S)-1-hydroxyethyl]benzonitrile (30-2).

Procedure:
A solution of benzyl (2R,5E)-2-[bis(tert-butoxycarbonyl)amino]-6-nitrohex-5-enoate from Step B (34.0 g, 73.2 mmol), 2,3-difluorophenylboronic acid (28.9 g, 183 mmol) and water (4.62 mL, 256 mmol) in dioxane (240 mL) was degassed with argon for 15 min. To this solution was added sodium bicarbonate (3.08 g, 36.6 mmol), (S)-BINAP (1.28 g, 2.05 mmol) and acetylacetanotobis(ethylene)rhodium(I) (0.472 g, 1.83 mmol). The mixture was stirred at ambient temperature for 2 min then heated to 35° C. After 4 h, (S)-BINAP (255 mg, 0.41 mmol) and acetylacetanotobis(ethylene)rhodium(I) (94 mg, 0.36 mmol) were added. After an additional 2 h, the reaction was partitioned between CH2Cl2 and aqueous NaHCO3. The aqueous layer was extracted with another portion of CH2Cl2. The combined organic extracts were dried over MgSO4, filtered and concentrated in vacuo. The crude product was purified by silica gel chromatography, eluting with a gradient of hexane:EtOAc—95:5 to 40:60, to give the title compound. MS: m/z=379 (M-C10H15O4).

Procedure:
A solution of 3-chlorocinnamoyl chloride (4g) in dry toluene (75 ml) was added with stirring to a solution of isobutylamine (12 ml) in dry benzene (200 ml). The reaction mixture was allowed to stand for 24 hours. The solvent was evaporated under reduced pressure and the residue thoroughly triturated with water, washed with dilute hydrochloric acid and then with water. The resulting crude product was recrystallized from ethanol-water (1:10) to give trans 3-chloro-N-isobutylcinnamamide (3.9 g), m.p. 111.5°-112.5° C. Elemental analysis, nmr and ir data were all consistent with the assigned structure. TLC gave one spot run on silica gel with 5:1 and 3:1 hexane:ethanol.

Procedure:
Potassium hydrogen carbonate (141 mg, 1.4 mmol) is added to a solution of 1-{3-[(R)-2-[3-(phenylsulphonylamino)-phenyl]-2-hydroxy-ethylamino]-3-methyl-butyl}-1H-indole-5-carboxylic acid-hydrotrifluoroacetate (Example 6; 300 mg, 0.47 mmol) in 2 ml DMF. Then the reaction mixture is stirred for 20 minutes at RT and 2-chloro-N,N-dimethylacetamide (143 mg, 1.18 mmol) is added. After 90 hours stirring at RT the reaction mixture is diluted with 50 ml of water and extracted with ethyl acetate. The organic phase is dried on magnesium sulphate and the solvent is eliminated in vacuo. The residue is chromatographed on silica gel (DCM/methanol=100:0→95:5).

Procedure:
To a solution of the title compound of Example 215 (23.0 mg, 0.0965 mmol) in dimethylformamide (0.75 mL) were added cesium carbonate (94 mg, 0.29 mmol) and methyl iodide (0.0072 mL, 0.12 mmol). After 4.5 h, the reaction was partitioned between dichloromethane (2 mL) and water (2 mL). The aqueous layer was extracted with dichloromethane (2 mL). The combined organic layers were dried (sodium sulfate) and concentrated in vacuo. The residue was taken up in a minimum amount of 50% aqueous methanol and loaded onto a methanol-activated water-equilibrated 1-g SCX-type cation exchange column. The column washed with water (6 mL) and 50% aqueous methanol (6 mL). The column was eluted with 2N methanolic ammonia (8 mL). This fraction was concentrated in vacuo to provide (−)-1,2,3,4,11,11a-hexahydro-2-methyl-pyrazino[1,2-b][1,2]benzothiazine 6,6-dioxide as a white solid (19 mg, 79%): LCMS (pos. ion spectrum) m/z 253.
