Procedure:
14-tert-Butoxycarbonylamino-18-(tert-butyl-dimethyl-silanyloxy)-2,15-dioxo-3,16-diaza-tricyclo[14.3.0.04,6]nonadec-7-ene-4-carboxylic acid (500 mg, 0.86 mmol.) was dissolved in 25 mL of THF and treated with CDI (180 mg, 1.12 mmol.). (Care was taken to avoid moisture by using oven dried glassware and maintaining a dry N2 atmosphere). After refluxing the reaction mixture for 2 h, it was cooled to rt and treated sequentially with cyclopropylsulfonamide (135 mg, 1.12 mmol.) and DBU (170 mg, 1.12 mmol.). The reaction mixture was stirred for 4 h at rt, and the THF was removed by rotary evaporation. The residue was partitioned between ethyl acetate and pH 4 buffer. The organic phase was dried (MgSO4) and concentrated in vacuo to give the crude product. It was then purified by flash chromatography (eluting with 33% ethyl acetate in hexane) to give 300 mg (51%) of [18-(tert-butyl-dimethyl-silanyloxy)-4-cyclopropanesulfonylaminocarbonyl-2,15-dioxo-3,16-diaza-tricyclo[14.3.0.04,6]nonadec-7-en-14-yl]-carbamic acid tert-butyl ester as a white solid. 1H NMR (300 MHz, CD3OD) δ 1H 0.07 (s, 3H), 0.08 (s, 3H), 0.85 (s, 9H), 0.87-1.49 (m, 21H), 1.73-1.95 (m, 3H), 2.08-2.16 (m, 1H), 2.25-2.36 (m, 2H), 2.42-2.56 (m, 1H), 2.85-2.93 (m, 1H), 3.65-3.74 (dd, J=10.61, 3.66 Hz, 1H), 3.89 (d, J=10.25 Hz, 1H), 4.34 (m, J=9.70, 9.70 Hz, 1H), 4.43 (t, J=7.87 Hz, 1H), 4.57 (s, 1H), 4.94-5.01 (m, 1H), 5.10 (d, J=8.78 Hz, 1H), 5.66-5.75 (m, 1H), 6.55 (s, 1H), 10.13 (s, 1H); MS m/z 683 (M++1).

Procedure:
In 20 ml of water is suspended 260 mg of 7β-amino-3-hydroxymethyl-3-cephem-4-carboxylic acid, and with ice-cooling and stirring, the suspension is adjusted to pH 7.0 with 1N-aqueous sodium hydroxide solution. After dissolution, 930 mg of 2-(2-tritylaminothiazol-4-yl)-(Z)-2-(trityloxyimino)acetic acid benzothiazol-2-ylthio ester, 20 ml of tetrahydrofuran, 20 ml of dioxane and 10 ml of acetonitrile are added and the mixture is stirred at room temperature for 38 hours. The reaction mixture is filtered and the filtrate is concentrated under reduced pressure. The residue is dissolved in 30 ml of tetrahydrofuran and the solution is subjected to silica gel (100 g) column chromatography. After the column is washed with acetonitrile (500 ml) and acetonitrile-water (19:1, 200 ml; 9:1, 200 ml), elution is carried out with 300 ml of acetonitrile-water (17:3). The eluate is concentrated under reduced pressure and the concentrate is freeze-dried to give 420 mg of sodium 7β-[2-(2-tritylaminothiazol-4-yl)-(Z)-2-(trityloxyimino)acetamido]-3-hydroxymethyl-3-cephem-4-carboxylate as light yellow powders.

Procedure:
In a 0.25 L reactor equipped with mechanical stirrer and thermometer, 100 ml of acetone was added. The reactor was maintained at room temperature (22° C.). 5.35 g of N-methyl piperazine (1.1 equivalents) followed by 4.16 g of NaOH solution (47%, 1 equivalent) were added. 20 g of 1-[[3-(4,7-Dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo[4,3-d]pyrimidin-5-yl)-4-ethoxyphenyl] sulfonyl chloride was added portion-wise (5 g each). The reaction mixture was kept at room temperature with mixing for 1 hour. The reaction mixture was kept at 5° C. for 2 hours. During that period, sildenafil base precipitated. After filtration, the cake was washed with water (50 ml). 29.24 g wet sildenafil base was obtained.

Procedure:
A degassed solution of phenylacetylene (3.9 ml, 35 mmol) and Et3N (36 mL) in DMF (13.5 mL) was added to N-[4-iodo-3-(trifluoromethyl)-1H-pyrazol-5-yl]acetamide (4.5 g, 14 mmol), CuI (530 mg, 2.8 mmol) and PdCl2(PPh3)2 (980 mg, 1.4 mmol) under an atmosphere of N2.

Procedure:
40 millimol of 1,4-naphthoquinone and 10 millimol of methyl 2-(N-methyl-1H-pyrrolyl)acetate were stirred in 50 ml of glacial acetic acid in a round-bottomed flask for 2 hours at room temperature. The reaction mixture was diluted with 300 ml of chloroform and the resulting mixture was then poured into a large volume of water (300 ml). The organic phase was then separated out and washed four times with 100 ml of water and finally with saturated aqueous NaCl solution. The resulting organic phase was dried over Na2SO4 and then concentrated under vacuum. The methyl [5-(1,4-dihydroxynaphthalen-2-yl)-1-methyl-1H-pyrrol-2-yl]acetate was thus isolated in a yield of 12% after purification by chromatography on a column of silica.

Procedure:
Under the argon atmosphere, to an ice-cooled solution of 2-aminobenzenethiol (0.20 ml, 1.87 mmole) in tetrahydrofuran (15 ml) was added 60% sodium hydride (76 mg, 1.90 mmole), and the mixture was stirred at room temperature for 30 minutes.

The reaction mixture was diluted with water, extracted with ethyl acetate, and washed with water and a saturated aqueous saline.

Procedure:
To a solution of tert-butyl nitrite (9.3 g, 90 mmol) and cupric chloride (9.7 g, 72 mmol) in 150 mL of acetonitrile at 65° C. was added portionwise ethyl 2-aminothiazole-5-carboxylate (10.3 g, 60 mmol) (prepared by the method of Dann, O. Chem Ber 76 419 (1943)) resulting in vigorous gas evolution. After the addition was complete, the solution was stirred until gas evolution ceased (30 minutes). The solution was cooled and poured into 250 mL of cold 20% v/v aqueous HCl. The aqueous solution was extracted 3 times with 200 mL of EtOAc. The organics were combined, washed once with 100 mL of 20% aqueous HCl and 2 times with 100 mL saturated brine and dried over magnesium sulfate. Concentration in vacuo gave 11.1 g (97% yield) of a brown oil which required no purification.

Procedure:
Triethylamine (3.86 mL, 10 eq) was added to a chilled (ice/water bath) suspension of N-[4-(4-amino-2-ethyl-1H-imidazo[4,5-c]quinolin-1-yl)butyl]methanesulfonamide (1.0 g, 1 eq) in N,N-dimethylformamide (DMF) (10 mL). Ethyl chloroformate (1.5 g, 5 eq) was added dropwise to give a clear solution. The reaction mixture was allowed to come to ambient temperature with stirring for 2 hours. Additional triethylamine (3.86 mL, 10 eq) and ethyl chloroformate (3.86 mL, 10 eq) were added and the reaction mixture was stirred overnight. The reaction mixture was poured onto crushed ice and then extracted with dichloromethane (50 mL). The organic layer was washed sequentially with water (2×50 mL), 4% sodium carbonate (50 mL), water (50 mL), and brine (50 mL) and then concentrated under reduced pressure. The residue was purified by automated flash chromatography (silica gel eluted with a linear gradient of 0-25% CMA in chloroform, 2500 mL) followed by recrystallization from acetonitrile to provide 0.815 g of ethyl 2-ethyl-1-{4-[(methylsulfonyl)amino]butyl}-1H-imidazo[4,5-c]quinolin-4-ylcarbamate as a white crystalline solid, mp 185-187° C.

Procedure:
To a suspension of 1-cyclohexylmethyl-7-methoxy-1H-indole-3-carboxylic acid (5 g, 17.4 mmol) in dichloromethane (100 ml) was added oxalyl chloride (3.04 ml, 34.8 mmol) and the resulting solution stirred overnight. Excess solvent and reagent were then removed by evaporation. To the resulting residue was added copper (I) cyanide (6.2 g, 69.6 mmol), toluene (200 ml) and acetonitrile (10 ml) and the resulting reaction mixture heated at reflux for 7 hours. A further portion of copper (I) cyanide (1.6 g, 17.9 mmol) was then added and the reaction mixture heated at reflux overnight. The reaction mixture was cooled and filtered through a pad of dicalite. The dicalite was washed with acetonitrile and the combined filtrate evaporated to leave a red solid. The solid was purified by flash column chromatography eluting with 50% (v/v) dichloromethane in heptane to afford (1-cyclohexylmethyl-7-methoxy-1H-indol-3-yl)-oxoacetonitrile (4.7 g, 14.7 mmol).
