Procedure:
A suspension of 5-chloro-1-(2-{4-[2-(4-methanesulfonyl-phenylcarbamoyl)-phenyl]-piperazin-1-yl}-2-oxo-ethyl)-1H-indole-2-carboxylic acid ethyl ester (0.14 g, 0.22 mmol) of in a 1:1:1 mixture of water/MeOH/1,4-dioxane (9 mL) is heated at 50° C. for 1 hour during which time all of the solids went into solution. The mixture is cooled to room temperature and concentrated under reduced pressure to remove volatile organics. The pH of the mixture is adjusted to slightly acidic (approx pH 5) by the addition of a 2N solution of hydrochloric acid which caused a solid to precipitate from solution. The formed solid is collected by filtration, washed with water and dried on the filter pad to provide 0.025 g of 5-chloro-1-(2-{4-[2-(4-methanesulfonyl-phenylcarbamoyl)-phenyl]-piperazin-1-yl}-2-oxo-ethyl)-1H-indole-2-carboxylic acid as an off white powder.

Triethylamine (approximately 3 ml) is added to a slurry of 5.0 g of 4,6-dimethylisothiazolo-(5,4-b)-pyridin-3(2H)-one in 120 ml reagent grade acetone until the mixture becomes homogeneous. A solution of 4.0 g (0.024 m) of benzyl bromide in 20 ml acetone is then added. The reaction mixture is stirred for 3 days at room temperature and is then stripped to dryness. The residue is washed once with deionized water, then with 95% 2B ethanol, then ether and dried to give the product.

Procedure:
An orange solution of tert-butyl 3-(5-(3-(6-isopropoxypyridin-2-yl)-1-tosyl-1H-indol-5-yl)-1,3,4-thiadiazol-2-ylamino)piperidine-1-carboxylate (38.6 mg, 0.056 mmol) and aq. NaOH (2.0 M, 0.1 mL, 0.200 mmol) in dioxane (1.0 mL) was heated at 100° C. for 30 min. Additional aq. NaOH (2.0 M, 0.1 mL, 0.200 mmol) was added, and the resulting mixture was stirred at 100° C. for 1.5 h. The mixture was then concentrated in vacuo, and the residue was taken up in HCl (4.0 M in dioxane; 1.0 mL, 4.00 mmol). The resulting yellow-orange mixture was stirred at 25° C. for 1 h, diluted with H2O (4 mL) and 1 N aq NaOH (3.5 mL). The resulting mixture was partitioned between DCM (30 mL) and saturated aq NaHCO3 (20 mL). The organic layer was separated, and the aqueous layer was extracted with DCM (20 mL). The combined organic extracts were dried over sodium sulfate, filtered, and concentrated in vacuo to provide crude 5-(3-(6-isopropoxypyridin-2-yl)-1H-indol-5-yl)-N-(piperidin-3-yl)-1,3,4-thiadiazol-2-amine as a light-yellow solid, which was taken up in DMSO (2.0 mL) and purified by reverse phase HPLC (10-100% AcCN/H2O+0.1% TFA) to provide 5-(3-(6-isopropoxypyridin-2-yl)-1H-indol-5-yl)-N-(piperidin-3-yl)-1,3,4-thiadiazol-2-amine 2,2,2-trifluoroacetate (12.0 mg, 0.022 mmol, 39%) as a yellow oil: MS (ESI, pos. ion) m/z: 435.2 (M+1). 1H NMR (400 MHz, MeOH-d4) δ ppm 11.38 (br s, 1H), 8.80 (d, J=1.2 Hz, 1H), 7.98 (s, 1H), 7.75-7.79 (m, 1H), 7.71-7.75 (m, 1H), 7.54 (d, J=8.6 Hz, 1H), 7.43 (d, J=7.4 Hz, 1H), 6.66 (d, J=8.2 Hz, 1H), 5.53 (dt, J=12.2, 6.1 Hz, 1H), 4.07-4.16 (m, 1H), 3.68 (dd, J=12.2, 3.6 Hz, 1H), 3.34-3.35 (obsc m, 1H), 3.09-3.15 (m, 1H), 3.02-3.08 (m, 1H), 2.18-2.27 (m, 1H), 2.10 (dt, J=15.0, 5.1 Hz, 1H), 1.83-1.92 (m, 1H), 1.73-1.82 (m, 1H), 1.49-1.51 (m, 3H), 1.49 (s, 3H).

Procedure:
7-Aminocephalosporanic acid (0.272 g) was added to the solution of potassium 1,2,5-thiadiazole-3-thiolate (0.136 g) in trifluoroacetic acid (5 ml) and the mixture was stirred for a few minutes until the solution turned clear, and then, boron trifluoride etherate (0.434 g) was added thereto and the mixture was stirred for 12 hours at room temperature. The reaction mixture was evaporated under reduced pressure and the residue was adjusted to pH 3.0 with 2% aqueous solution of ammonium hydroxide. The precipitates were collected by filtration, washed with cool water, acetone and diethyl ether and dried to give 7-amino-3-(1,2,5-thiadiazol-3-yl)thiomethyl-3-cephem-4-carboxylic acid (0.210 g).
