Procedure:
A suspension mixture of benzyloxycarbonylpiperazine (14.529, 65.9 mmol), 3-dimethyl-aminopropyl chloride hydrochloride (15.63 g, 98.9 mmol), and triethylamine (20.29, 200 mmol) in ethanol (100 ml) was refluxed for 14 h. Then 3-dimethylaminopropyl chloride hydrochloride (6.32 g, 40 mmol), and triethylamine (11.3 ml, 80 mmol) was added to the reaction mixture and continued to reflux for 24 h. The solvent was evaporated and the residue was extracted with ethyl actate.

Procedure:
To a mixture of 3-methylthio-1-propanol tosylate (14.14 g, 54.3 mmol), and 3-mercapto-1-propanol (5.0 g, 54.3 mmol) in dry THF (300 mL) was added potassium tert-butoxide (8.51 g, 80.0 mmol) in one portion under a blanket of nitrogen, and the resulting mixture was stirred at room temperature for 24 hours. Water (10 mL) was added drop-wise to the reaction mixture to quench excess potassium tert-butoxide, and solvent was evaporated under reduced pressure. The resulting solid was washed with ether (3×100 mL), and filtered. The ether layer was washed with water (3×100 mL) and dried (Na2SO4). Solvent evaporation produced 8.7 g of a light yellow oil. This product was used for acryloylation without further purification.

It was warmed to −10° C. during 45 min and stirred at this temperature for another 30 min. The mixture was cooled again below −60° C. followed by dropwise addition of triisopropyl borate (41.4 g, 220.21 mmol). After warming to room temperature the mixture was quenched with hydrochloric acid (70 mL, 2N) and stirred for 1 h. The alkaline aqueous layer was brought to pH 5 and extracted with ethyl acetate (3×80 mL). All organic layers were combined, dried over sodium sulfate, and concentrated in vacuo to give 5-fluorobenzofuran-2-ylboronic acid (3.5 g, 26%) which was used for the next step without further purification.

Procedure:
To a solution of methyl [1-(hydroxymethyl)cyclopropyl]acetate (1 eq.) from the previous step in DCM (0.1 M) at −40° C. was added triethylamine (3 eq.) and then methanesulfonyl chloride (1.5 eq.). The reaction was warmed to 0° C. over 1 h, and it was diluted with DCM and quenched with saturated aqueous NaHCO3. The aqueous phase was extracted with DCM. The combined organic extracts were dried over MgSO4 and concentrated in vacuo. The crude product was purified by flash column chromatography (SiO2, 0%→50% EtOAc in Hex) to afford the title compound appendage 3 as an oil.

Procedure:
15.3 g of sodium hydride (65% dispersion in mineral oil, 0.414 moles) was suspended in 250 ml of N,N-dimethylformamide at 10° C. To this suspension, 100 g of 4-benzyl-2-oxo-3-phenylpiperazine (0.376 moles) was added portionwise over a period of 30 min and stirred for 15 min. A solution of 64 g of methyl iodide (0.45 moles) in 50 ml of N,N-dimethylformamide was added slowly in 45 min maintaining the temperature below 25° C. and maintained for 1 hour. After completion of the reaction, mass was poured slowly in 1000 ml of cold water (15° C.). The product was extracted with toluene (1×500 ml, 1×300 ml) from aqueous phase. Toluene layer was washed with water (2×200 ml) and concentrated. To the residue, 250 ml of cyclohexane was added and cooled to 10° C. with stirring. Filtered the product and washed with precooled cyclohexane to obtain 98.5 g of 4-benzyl-1-methyl-2-oxo-3-phenylpiperazine product (yield: 93.8%, purity: 99.15 by HPLC)

Procedure:
0.76 g (3.7 mmol) of 1-methyl-2-oxo-1,2-dihydroquinoline-3-carboxylic acid was dissolved in dichloromethane (50 mL), and 1.0 mL (12 mmol) of oxalyl chloride was added to the above solution. Two droplets of N,N-dimethylformamide were added to this mixture, and the resulting mixture was stirred for 1 hour at 40° C. The reaction solution was concentrated under reduced pressure, and thus 1-methyl-2-oxo-1,2-dihydroquinoline-3-carboxylic acid chloride was obtained. The acid chloride thus obtained was dissolved in acetonitrile (30 mL), and this solution was added to an acetonitrile (50 mL) solution of 0.46 g (4.1 mmol) of 1,3-cyclohexanedione and 0.63 mL (4.5 mmol) of triethylamine under ice cooling. The mixture was stirred overnight at room temperature. This reaction mixture was poured into water and was extracted with ethyl acetate. The organic phase was washed with water, an aqueous solution of sodium hydrogen carbonate, and water in this order, and then was dried and concentrated. The residue was purified by column chromatography (ethyl acetate:n-hexane=1:4 to 1:0), and thus 0.48 g (yield: 43%) of the title compound was obtained as a pale yellow powder.

Procedure:
Under a nitrogen atmosphere, a stirred solution of 1.8 grams (0.007 mole) of 2-amino-3-cyano-5-iodo-4-methylpyridine, 2.3 grams (0.007 mole) of (2,3-dihydro-2,2-dimethyl-3-benzofuranon-4-yl)trimethyltin (prepared in Step D of this Example), and 0.5 gram (catalyst) of tetrakis(triphenylphosphine)palladium(0) in 25 mL of toluene is heated at reflux for about 22 hours. After this time the reaction mixture is cooled to ambient temperature and diluted with 50 mL of ethyl acetate. The mixture is filtered through diatomaceous earth, and the filtrate is concentrated under reduced pressure to a residue. The residue is purified using column chromatography, yielding 2-amino-3-cyano-4-methyl-5-(2,3-di hydro-2,2-dimethyl-3-benzofuranon-4-yl)pyridine.

Procedure:
To a solution of 2-propyl-1-heptanol (0.81 g, 5.1 mmol) in dry CH2Cl2 (15 mL) was added dropwise a solution of trifluoromethanesulfonic anhydride (1.77 g, 6.10 mmol) in the same solvent (5 mL). After stirring at room temperature for 20 min, the reaction mixture was poured into ice (40 mL) and neutralized with saturated aqueous NaHCO3 solution. The organic layer was separated, washed with water, dried over anhydrous Na2SO4, filtered, and concentrated in vacuo to yield nearly pure 2-propyl-1-heptyl triflate as a purple liquid (1.40 g, 94.1%). The 2-propyl-1-heptyl triflate (0.319 g, 1.10 mmol) was next added dropwise to a solution of 15 (0.275 g, 1.00 mmol) in dry CH2Cl2 (10 mL), and the reaction mixture was stirred at room temperature for 12 h. A solution of sodium methoxide in methanol (2.4 mL, 0.5 M) was then added dropwise to the resulting solution of pyridinium salt 17. The color of the mixture immediately changed from yellow to purple. After stirring at room temperature for 10 min, the solvent was removed under reduced pressure. The resulting purple solid was then partitioned between water (20 mL) and CH2Cl2 (20 mL). The organic layer was separated, dried over anhydrous Na2SO4, filtered, and concentrated in vacuo. The crude product was next purified by flash chromatography on silica gel eluting with 4:100 methanol: CH2Cl2, to give 0.278 g (66.9%) of the title compound as an orange solid: mp 276-278° C.; 1H NMR (400 MHz, DMSO-d6): δ 8.969 (s, 2H), 6.591 (s, 2H), 4.421 (t, 2H, J=5.6 Hz), 2.114 (m, 1H), 2.067 (s, 6H), 1.704 (s, 6H), 1.229-1.190 (m, 12H), 0.836 (m, 6H); 13C NMR (125 MHz, DMSO-d6): δ 159.170, 142.273, 142.082, 137.669, 132.328, 125.659, 122.083, 117.561, 63.995, 38.500, 32.713, 31.339, 30.165, 27.600, 25.025, 21.849, 19.165, 18.846, 16.653, 14.188, 13.897; MS (high resolution, EI): m/z 415.2985 [M+]; calcd, 415.2987; Anal.
